FR60 MB91301 Series MB91302A/V301A
 DESCRIPTION
The MB91301 series are a line of microcontrollers based on a 32-bit RISC CPU core (FR family) , incorporating a variety of I/O resources and a bus control mechanism for embedded control that requires the processing of a high-performance, fast CPU as well as an SDRAM interface that can connect SDRAM directly to the chip. The large address space supported by the 32-bit CPU addressing means that operation is primarily based on external bus access although instruction cache memory of 4 Kbytes and RAM of 4 Kbytes( for data) are included for high-speed execution of CPU instructions. The MB91302A and MB91V301A are FR60 products based on the FR30/40 CPU with enhanced bus access for higher speed operation. The device specifications include a D/A converter to facilitate motor control and are ideal for use in DVD players that support fly-by transfer.
 FEATURES

 HANDLING DEVICES
MB91301 series * Operation at start-up Always apply a settings initialization (INIT) to the INIT pin immediately after turning on the power. Also, in order to provide a delay while the oscillator circuits stabilize immediately after start-up, maintain the "L" level input to the INIT pin for the required stabilization delay time. (The initialization processing (INIT) triggered by the INIT pin initializes the oscillation stabilization delay time to the minimum setting.) * External clock input at start-up At power-on start-up, always input a clock signal until the oscillation stabilization delay time is ended. * Output indeterminate at power-on time When the power is turned on, the output pin may remain indeterminate until the internal power supply becomes stable. * Built-in DC/DC regulator This device has a built-in regulator, requiring 3.3 V input to the Vcc pin and a bypass capacitor of approximately 4.7 F connected to the C pin for the regulator.

* Preventing Latchup When CMOS integrated circuit devices are subjected to applied voltages higher than VCC at input and output pins, or to voltages lower than VSS, as well as when voltages in excess of rated levels are applied between VCC and VSS, a phenomenon known as latchup can occur. When a latchup condition occurs, the supply current can increase dramatically and may destroy semiconductor elements. In using semiconductor devices, always take sufficient care to avoid exceeding maximum ratings. * Power supply pins Devices with multiple VCC and VSS supply pins are designed to prevent problems such as latchup occurring by providing internal connections between pins at the same potential. However, in order to reduce unwanted radiation, prevent abnormal operation of strobe signals due to a rise in ground level, and to maintain the total output current ratings, all such pins should always be connected externally to power supply or ground. Also, ensure that the impedance of the VCC and VSS connections to the power supply are as low as possible. In addition, it is recommended that a bypass capacitor of approximately 0.1F be connected between VCC and VSS. Connect the capacitor close to the VCC and VSS pins. * Crystal oscillators Noise in proximity to the X0 and X1 pins can cause abnormal operation in this device. Printed circuit boards should be designed so that the X0 and X1 pins, crystal (or ceramic) oscillator, and bypass capacitor connected to ground are placed as close together as possible. Also, to ensure stable operation, it is strongly recommended that the printed circuit board art work be designed such that the X0 and X1 pins are surrounded by ground. Please ask the crystal maker to evaluate the oscillational characteristics of the crystal and this device. * Treatment of NC and OPEN pins Pins marked as "NC" or "OPEN" must be left open-circuit. * Treatment of unused input pins If unused input pins are left open, abnormal operation may result. Any unused input pins should be connected to pull-up or pull-down resistors. * Mode pins (MD0 to MD2) These pins should be connected directly to VCC or VSS. To prevent the device erroneously switching to test mode due to noise, design the printed circuit board such that the distance between the mode pins and VCC or VSS is as short as possible and the connection impedance is low. * Remarks for External Clock Operation When external clock is selected, supply it to X0 pin generally, and simultaneously the opposite phase clock to X0 must be supplied to X1 pin. However, in this case the stop mode must not be used (because X1 pin stops at "H" output in stop mode) . When operating at 12.5 MHz or less, the microcontroller can be used with the clock signal supplied only to pin X0. "Using an external clock (normal) and (12.5 MHz) " shows examples of how the MB91301 uses the external clock.

* Notes on during operation of PLL clock mode If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed. * Clock control block For L-level input to the INIT pin, allow for the regulator settling time or oscillation settling time. * Bit search module The 0-detection, 1-detection, and transition-detection data registers (BSD0, BSD1, and BSDC) are only wordaccessible. * I/O port access Byte access only for access to port * Shared port function switching To switch a pin that also serves as a port, use the port function register (PFR). Note, however, that bus pins are switched depending on external bus settings. * D-bus memory Do not set a code area in D-bus memory. No instruction fetch is performed to the D-bus. Instruction fetches to the D-bus area result in incorrect data interpreted as code, which can cause the microcontroller to lose control. Do not set a data area in I-bus memory. 24
MB91301 Series
* I-bus memory Do not set a stack area or vector table in I-bus memory. It may cause a hang during EIT processing (including RETI). Recovery from the hang requires a reset. Do not perform DMA transfer to I-bus memory. * Low-power consumption modes * To enter the standby mode, use the synchronous standby mode (set with the SYNCS bit as bit 8 in the TBCR, or time-base counter control register) and be sure to use the following sequence: (LDI #value_of_standby, R0) (LDI #_STCR, R12) STB R0, @R12 ; Write to standby control register (STCR) LDUB @R12, R0 ; Read STCR for synchronous standby LDUB @R12, R0 ; Read STCR again for dummy read NOP ; NOP x 5 for timing adjustment NOP NOP NOP NOP * If you use the monitor debugger, follow the precautions below: Do not set a breakpoint within the above array of instructions. Do not single-step the above array of instructions. * Prefetch When accessing a prefetch-enabled little endian area, use word access only (access in 32 bits). Byte or halfword access results in wrong data read. * MCLK and SYSCLK MCLK causes a stop in SLEEP/STOP mode while SYSCLK causes a stop only in STOP mode. Use either depending on each application. * Pull-up control When function pins listed in the AC specifications (such as external bus control pins) have pull-up control, enabling the pull-up resistor for a pin causes the actual pin load conditions to change. As all AC specifications for this device were measured under the condition of pull-up resistors disabled, the values are not guaranteed of AC specifications when pull-up resistors are enabled. Even if the pull-up resistor is set to enabled for a pin, if the HIZ bit in the standby control register (STCR) specifies setting output pins to high impedance during stop mode (HIZ = 1) , changing to stop mode (STOP = 1) causes the pull-up resistor to be disabled.

* R15 (General purpose register) When any of the following instructions is executed, the SSP* or USP* value is not used as R15, resulting in an incorrect value written to memory. AND R15, @Ri ANDH R15, @Ri ANDB R15, @Ri OR R15, @Ri ORH R15, @Ri ORB R15, @Ri EOR R15, @Ri EORH R15, @Ri EORB R15, @Ri XCHB @Rj, R15 * : R15 is a virtual register. When a program attempts to access R15, the SSP or USP is accessed depending on the status of the "S" flag as an SP flag. When coding the above ten instructions using an assembler, specify a general-purpose register other than R15. * RETI instruction Please do not neither control register of the instruction cache nor the data access to RAM of the instruction cache immediately before the instruction of RETI. * Notes on the PS register Since some instructions manipulate the PS register earlier, the following exceptions may cause the interrupt handler to break or the PS flag to update its display setting when the debugger is being used. As the microcontroller is designed to carry out reprocessing correctly upon returning from such an EIT event, it performs operations before and after the EIT as specified in either case. * The following operations may be performed when the instruction immediately followed by a DIVOU/DIVOS instruction is (a) halted by a user interrupt or NMI, (b) single-stepped, or (c) breaks in response to a data event or emulator menu: (1) D0 and D1 flags are updated earlier. (2) The EIT handler (user interrupt/NMI or emulator) is executed. (3) Upon returning from the EIT, the DIVOU/DIVOS instruction is executed and the D0 and D1 flags are updated to the same values as those in (1) above. * The following operations are performed when the ORCCR/STILM/MOV Ri and PS instructions are executed to enable interruptions when a user interrupt or NMI trigger event has occurred. (1) The PS register is updated earlier. (2) The EIT handler (user interrupt/NMI or emulator) is executed. (3) Upon returning from the EIT, the above instructions are executed and the PS register is updated to the same value as that in (1) above. * A/D converter When the device is turned on or returns from a reset or stop, it takes time for the external capacitor to be charged, requiring the A/D converter to wait for at least 10 ms. * Watchdog timer The watchdog timer function of this model monitors that a program delays a reset within a certain period of time and resets the CPU if the program fails to delay it, for example, because the program runs out of control. Once the watchdog timer function is enabled, therefore, the watchdog timer continues to operate until a reset takes place. An exception, for example during stop, sleep and DMA transfer modes, is the automatic delaying of a reset under a condition in which the CPU stops program execution. Note, however, that a watchdog reset may not occur in the above state caused when the system runs out of control. If this is the case, use the external INIT pin to cause a reset (INIT) .

Unique to the evaluation chip MB91V301A * Tool reset On an evaluation board, use the chip with INIT and TRST connected together. * Simultaneous occurrences of a software break and a user interrupt/NMI When a software break and a user interrupt /NMI take place at the same time, the emulator debugger can cause the following phenomena: * The debugger stops pointing to a location other than the programmed breakpoints. * The halted program is not re-executed correctly. If these phenomena occur, use a hardware break instead of the software break. If the monitor debugger has been used, avoid setting any break at the relevant location. * Single-stepping the RETI instruction If an interrupt occurs frequently during single stepping, execute only the relevant processing routine repeatedly after single-stepping RETI. This will prevent the main routine and low-interrupt-level programs from being executed. Do not single-step the RETI instruction for avoidance purposes. When the debugging of the relevant interrupt routine becomes unnecessary, perform debugging with that interrupt disabled. * Operand break A stack pointer placed in an area set for a DSU operand break can cause a malfunction. Do not apply a data event break to access to the area containing the address of a system stack pointer. * ICE startup sequence When using the ICE, when you start debugging, ensure that the bus configuration is set correctly for the area being used before downloading. After turning on the power to the target, the states of the RD and WR0 to WR3 pins are undefined until you perform the above setting. Accordingly, include enabling pull-up as part of the startup sequence. If using these pins as general-purpose ports, set as output ports to prevent conflict with the output signals during the time the pin states are undefined.

1. Memory Space
The FR family has 4 Gbytes (232 addresses) of logical address space with linear access from the CPU. * Direct Addressing Areas The following areas of address space are used for I/O operations. These areas are called direct addressing areas, in which the address of an operand can be specified directly during an instruction. The direct areas differ according to the size of the data accessed, as follows.  byte data access : 000H to 0FFH  half word data access : 000H to 1FFH  word data access : 000H to 3FFH

 MODE SETTINGS
In the FR series, the mode is set by the mode pins (MD2, MD1, and MD0) and mode register (MODR).
1. Mode Pins
The MD2, MD1, and MD0 pins specify how the mode vector fetch is performed. Mode Pins Reset vector access Mode name area MD2 MD1 MD0 0 0 0 0 0 1 Internal ROM vector mode External ROM vector mode Internal External
Remarks
Single-chip mode* The bus width is specified by the mode register.
Values other than those listed in the table are prohibited. * : Single chip mode is able to set only MB91302A.
2. Mode Register (MODR)
* Details of mode register (MODR) The data written to the mode register by the mode vector fetch operation (see "3.11.3 reset sequences") is called the mode data. After the data is set to the mode register (MODR), the device operates with the operating mode specified by this data. The mode register is set by all types of reset. The register cannot be written to by user programs.

* Operating mode Bus mode Single chip Internal ROM external bus External ROM external bus
Access mode 32-bit bus width 16-bit bus width 8-bit bus width
* Bus mode The bus mode controls the operations of internal ROM and the external access function. It is specified with the mode setting pins (MD2, MD1, and MD0) and the ROMA bit in mode data. * Access mode The access mode controls the external data bus width. It is specified with the WTH1 and WTH0 bits in the mode register and the DBW1 and DBW0 bits in area configuration registers 0 to 7 (ACR0 to ACR7). * Bus Modes The FR family has three bus modes: bus mode 0 (single-chip mode), bus mode 1 (internal-ROM, external-bus mode), and bus mode 2 (external-ROM, external-bus mode). The MB91V301A supports only bus mode 2 (external-ROM, external-bus mode). See "1. Memory Space" in CPU for details. * Bus mode0 (single chip mode) (only MB91302A) The internal I/O, 4 Kbytes D-bus RAM, 32 Kbytes F-bus RAM (FRAM) and 96 Kbytes F-bus ROM are valid, while access to any other areas is invalid under this mode. The function of external pin is peripheral or generalpurpose port. The pin can not be used as the bus pin. * Bus mode 1 (internal ROM external bus mode) The internal I/O, D-bus RAM, F-bus RAM (FRAM) and F-bus ROM are valid, and access to areas where external access is enabled will access external space under this mode. A part of an external terminal functions as a bus terminal. * Bus mode 2 (External-ROM, external-bus mode) This mode enables internal I/O and D-bus RAM, in which any access is access to external space. Some external pins serve as bus pins.

*1 : ICRs are registers built in the interrupt controller to set interrupt levels for individual interrupt requests. The ICRs are provided for the different interrupt levels. *2 : The TBR is the register holding the start address of the EIT vector table. The TBR value and the offset value preset for each EIT source are added together to be the vector address. Note: The 1 Kbyte area from the TBR address is the EIT vector area. The vector size is 4 bytes and the relationship between vector number and vector address is expressed as follows: Vctadr = TBR + vctofs = TBR + (3FCH - 4 x vct) vctadr : vector address vctofs : vector offset vct : vector number

 INSTRUCTION CACHE
The instruction cache is a fast local memory for temporary storage. Once an instruction code is accessed from external slower memory, the instruction cache holds the instruction code inside to increase the speed of accessing the same code from then on. By setting the RAM mode, the instruction cache data RAM is made directly read/write-accessible by software. * Configuration * FR family's basic instruction length : Two bytes * Block layout : Two-way set associative * Blocks : 128 blocks per way 16 bytes per block ( = 4 sub-blocks) 4 bytes per sub-block ( = 1 bus access unit) * Instruction Cache Configuration

[bit 31 to bit 9] Address tag The address tag stores the upper 23 bits of the memory address of the instruction cached in the corresponding block. For example, memory address IA of the instruction data stored in sub-block k in block i is obtained from the following equation: IA = address tag x 29 + i x 24 + k x 22 The address tag is used to check for a match with the instruction address requested for access by the CPU. The CPU and cache behave as follows depending on the result of the tag check: * When the requested instruction data exists in the cache (hit), the cache transfers the data to the CPU within the cycle. * When the requested instruction data does not exist in the cache (miss), the CPU and cache obtain the data loaded by external access at the same time.
[bit 7 to bit4] SBV3 to SBV0 : Sub-block validation When SBVn contains "1", the corresponding sub-block holds the current instruction data at the address located by the tag. Each sub-block usually holds two instructions (excluding immediate-value transfer instructions). [bit 3] TAGV : Tag validation bit This bit indicates whether the address tag value is valid. When the bit contains "0", the corresponding block is invalid regardless of the settings of the sub-block validation bits. (The bit is set to "0" when the cache is flushed.) [bit 1] LRU (only in way 1) This bit exists only in the instruction cache tag in way 1. The bit indicates way 1 or 2 as the way containing the last entry accessed in the selected set. When set to "1", the LRU bit indicates that the entry of the set in way 1 is the last entry accessed. When set to "0", it indicates that the one in way 2 is the last entry accessed. [bit 0] ETLK : Entry lock This bit is used to lock all the entries in the block corresponding to the tag in the cache. When the ETLK bit is set to "1", the entries are locked and are not updated when a cache miss occurs. Note, however, that invalid sub-blocks are updated. If a cache miss occurs with both of ways 1 and 2 in the entry lock states, access to external memory takes place after losing one cycle used for evaluating the cache miss. 53

 PERIPHERAL RESOURCES
1. External Bus Interface Controller
* External Bus Interface Controller Features * Maximum output address width = 32-bit (4 Gbytes memory space) * Various different types of external memory (8-bit, 16-bit, or 32-bit devices) can be directly connected and the controller can support multiple devices with different access timings. Asynchronous SRAM, asynchronous ROM/FLASH memory (supports multiple write strobe access or byteenable access) Page mode ROM/FLASH memory (2, 4, or 8 page size) Burst mode ROM/FLASH memory Address/data multiplexed bus (8-bit or 16-bit width only) Synchronous memory (built-in ASIC memory, etc.) Note: Synchronous SRAM cannot be directly connected. * Memory can be divided into eight independent banks (chip select areas) with a separate chip select output for each bank. The size of each area can be set in 64 Kbytes increments (the size of each chip select area can range from 64 Kbytes to 2 Gbytes) Each area can be located anywhere in the physical address space (subject to boundary limitations based on the area size) * The following functions can be set independently for each chip select area : Chip select area enable/disable (Access is not performed to disabled areas) Setting of an access timing type to support each type of memory (For SDRAM, only the CS6 and CS7 areas can be connected.) Detailed access timing settings (wait cycles and similar settings for each access type) Data bus width (8-bit, 16-bit, 32-bit) Byte-ordering setting (big or little endian) Note: The CS0 area must be big endian. Write-prohibit setting (read-only areas) Enable or disable loading into built-in cache Enable or disable prefetch function Maximum burst length setting (1, 2, 4, 8) * Different detailed timing settings can be set for each timing type Even for the same type, different settings can be used for each chip select area. Up to 15 auto-wait cycles can be specified. (For asynchronous SRAM, ROM, Flash, and I/O areas) The bus cycle can be extended by the external RDY input. (For asynchronous SRAM, ROM, Flash, and I/O areas) Fast access wait and page wait settings are supported (For burst/page mode ROM and Flash areas) Idle cycles, recovery cycles, setup delays, and similar can be inserted. Capable of setting timing values such as the CAS latency and RAS-CAS delay (SDRAM area) Capable of controlling the distributed/centralized auto-refresh, self-refresh, and other refresh timings (SDRAM area) * DMA supports fly-by transfer Transfer between memory and I/O can be performed by a single access. Memory wait cycles can be synchronized with the I/O wait period during fly-by transfer. Hold times can be maintained by extending access to the data source only. Separate idle and recovery cycle settings can be specified for use in fly-by transfer. * Supports external bus arbitration using BRQ and BGRNT. * Pins not used by the external interface can be set as general purpose I/O ports.

2. I/O Ports

PDR : Port Data Register DDR : Data Direction Register PFR : Port Function Register PCR : Pull-up Control Register
Note : For port output, the pull-up resistor is disabled irrespective of the setting. I/O ports with pull-up resistors have the following registers : * PDR (Port Data Register) * DDR (Data Direction Register) * PFR (Port Function Register) * PCR (Pull-up Control Register) I/O ports have three following modes * When port is in input mode (PFR = "0" & DDR = "0") PDR read : Reads the level of the corresponding external pin. PDR write : Writes the value to the PDR. * When port is in output mode (PFR = "0" & DDR = "1") PDR read : Reads the PDR value. PDR write : Outputs the PDR value to the corresponding external pin. * When port is in peripheral output mode (PFR = "1" & DDR = "X") PDR : Reads the value of the corresponding peripheral output. PDR write : Writes the value to the PDR. 60
MB91301 Series
Notes : * Use byte access to access ports. * The external bus function has priority for port 0 to port A when these are used as external bus pins. Accordingly, writing to the DDR has no effect on the pin input/output setting while the pins are operating as external bus pins. The value set in the DDR becomes meaningful when the PFR register is modified to set the pins as general purpose ports. * In stop mode (HIZ = 0), the pull-up resistor control register setting is used. * In stop mode (HIZ = 1), the pull-up resistor control register (PCR) setting is ignored during hardware standby. * Using pull-up resistors is prohibited when these pins are used as external bus pins. In this case, do not write "1" to the corresponding bit in the pull-up resistor control register (PCR).

The PPG timer can output highly precise PWM waveforms efficiently. The MB91301 series contains four channels of PPG timer. * Features of the PPG Timer * Each channel consists of a 16-bit down counter, a 16-bit data register with cycle setting buffer, a 16-bit compare register with duty setting buffer, and pin control section. * The count clocks for the 16-bit down counter can be selected from the following four types : Internal clock , /4, /16, /64 * The counter is initialized to "FFFFH" at a reset or counter borrow. * Each channel has a PPG output. * Register outline Cycle setting register: Reload data register with buffer Duty setting register: Compare register with buffer Transfer from the buffer takes place upon a counter borrow. * Pin control overview A duty match sets the pin control section to 1. (Preferential) A counter borrow resets it to 0. The output value fix mode is available, which can each output all "L" (or "H"). A polarity can also be specified. * An interrupt request can be generated at a combination of the following events : Activation of the PPG timer Counter borrow (cycle match) Duty match Counter borrow (cycle match) or duty match DMA transfer can be initiated by the above interrupt request. * It is possible to set the simultaneous activation of two or more channels by means of software or another interval timer. Restarting during operation can also be set. * The request level to be detected can be selected from among "rising edge", "falling edge", and "both edges".

8. U-TIMER (16 bit timer for UART baud rate generation)
The U-TIMER is a 16-bit timer used to generate the baud rate for the UART. Any desired baud rate can be set using the combination of the chip operating frequency and U-TIMER reload value. The U-TIMER can also be used as an interval timer by generating an interrupt from a count underflow event. The MB91301 series has three U-TIMER channels. When used as an interval timer, two U-TIMER channels can be connected in cascade for a maximum count interval of up to 232 x . Cascade connection is only available for ch0 and ch1 or ch0 and ch2. * Block Diagram

14. Input Capture
This module has a function that detects a rising edge, falling edge or both edges and holds a value of the 16-bit free-run timer in a register at the time of detection. It can also generate an interrupt when detecting an edge. The input capture consist of input capture and control registers. Each input capture have the corresponded external input pins. * The valid edge of the external input can be selected from three types : Rising edge Falling edge Both edges * It can generate an interrupt when it detects the valid edge of the external input.

 PIN STATUS IN EACH CPU STATE
* Terms used in the pin status list * Input ready Indicates that the input function can be used. * Input 0 fixed Indicates that the input level has been internally fixed to be 0 to prevent leakage when the input is released. * Output Hi-Z Indicates to put the pin in a high impedance state with the pin driving transistor disabled for driving. * Output held Indicates the output in the output state existing immediately before this mode is established. If the device enters this mode with an internal output peripheral operating or while serving as an output port, the output is performed by the internal peripheral or the port output is maintained, respectively. * Previous state held When the device serves for output or input immediately before entering this mode, the device maintains the output or is ready for the input, respectively.
