s DESCRIPTION
The MB91107 is a standard single-chip microcontroller constructed around the 32-bit RISC CPU (FR* family) core with abundant I/O resources and bus control functions optimized for high-performance/high-speed CPU processing for embedded controller applications. To support the vast memory space accessed by the 32-bit CPU, the MB91107 normally operates in the external bus access mode and executes instructions on the internal 1 Kbyte cache memory and RAM (MB91107: 128 Kbytes, MB91108: 160 Kbytes) for enhanced performance. The MB91107 is optimized for applications requiring high-performance CPU processing such as navigation systems, high-performance FAXs and printer controllers. *: FR Family stands for FUJITSU RISC controller.

s HANDLING DEVICES
1. Preventing Latchup
In CMOS ICs, applying voltage higher than VCC or lower than VSS to input/output pin or applying voltage over rating across VCC and VSS may cause latchup. This phenomenon rapidly increases the power supply current, which may result in thermal breakdown of the device. Make sure to prevent the voltage from exceeding the maximum rating.
2. Treatment of Pins
*Treatment of unused pins Unused pins left open may cause malfunctions. Make sure to connect them to pull-up or pull-down resistors. *Handling the output pins Connecting an output pin to the power supply, to another output pin, or to a large-capacitance load may cause a large current to flow. Since letting it flow for an extended period of time degrades the device, be careful in using the device not to exceed the maximum rating. *Power supply pins When there are several VCC and VSS pins, each of them is equipotentially connected to its counterpart inside of the device, minimizing the risk of malfunctions such as latch up. To further reduce the risk of malfunctions, to prevent EMI radiation, to prevent strobe signal malfunction resulting from creeping-up of ground level and to observe the total output current standard, connect all VCC and VSS pins to the power supply or GND. It is preferred to connect VCC and VSS of MB91107 to power supply with minimal impedance possible. It is also recommended to connect a ceramic capacitor as a bypass capacitor of about 0.1 F between VCC and VSS at a position as close as possible to MB91107. *Mode setting pins (MD0 to MD2) Connect mode setting pins (MD0 to MD2) directly to VCC or VSS. Arrange each mode setting pin and VCC or VSS patterns on the printed circuit board as close as possible and make the impedance between them minimal to prevent mistaken entrance to the test mode caused by noises. *Crystal oscillator circuit Noises around X0 and X1 pins may cause malfunctions of MB91101. In designing the PC board, layout X0, X1 and crystal oscillator (or ceramic oscillator) and bypass capacitor for grounding as close as possible. It is strongly recommended to design PC board so that X1 and X0 pins are surrounded by grounding area for stable operation.
3. Notes on Use
*External reset input The RST pin requires "L" level input for at least five machine cycles before the the internal circuitry can be completely reset. *External clock To use an external clock, in principle, supply the X0 and X1 pins with a clock signal opposite in phase to the X0. To use the STOP mode (oscillation stop mode) along with the external clock, in which the X1 pin stops with "H" output, you should insert an external resistor of about 1 kilohm to prevent a collision between outputs. Given the next page is an example of using an external clock.

Note: To use the STOP mode (oscillation stop mode), insert a resistor to the X1 pin.
4. Notes on Internal DC-DC Regulator
* Since this product contains a regulator, be sure to supply current at 3.3 V to the VCC pin and insert a bypass capacitor of about 0.1 F to the C pin for the regulator. * The A/D converter requires a 3.3-V power supply separately.
*Connecting to power supply
3.3 V VCC AVCC AVRH AVSS GND VSS C
15
MB91107/108
* Notes on using the STOP mode The regulator built in this product stops in the STOP mode. If the regulator stops due to a malfunction caused by noise or a fault in the power supply during normal operation, the internal 2.5-V power supply may go below the lower limit of the guaranteed operating voltage range. When using the STOP mode with the internal regulator, therefore, be sure to supply an auxiliary external power to prevent the 3.3-V power supply from coming down. Even in that case, the internal regulator can be restarted by input of a reset signal (To restart the regulator, keep the reset pin at the L level for at least the oscillation settling time).

5. Turning on the Power Supply
*RST pin When turning on the power supply, never fail to start from setting the RST pin to "L" level. And after the power supply voltage goes to VCC level, at least after ensuring the time for 5 machine cycles, then set to "H" level. *Pin Condition at Turning on the Power Supply The pin condition at turning on the power supply is unstable. The circuit starts being initialized after turning on the power supply and then starting oscillation and then the operation of the internal regulator becomes stable. So it takes about 42 ms for the pin to be initialized from the oscillation starting at the source oscillation 12.5 MHz. Take care that the pin condition may be output condition at initial unstable condition. (With the MB91107, however, initalization can be achieved in less than about 42 ms after turning on the internal power supply by maintaining the RST pin at "L" level.) *Source Oscillation Input at Turning on the Power Supply At turning on the power supply, never fail to input the clock before cancellation of the oscillation stabilizing waiting. *Hardware Stand-by at Turning on the Power Supply When turning on the power supply with the HST pin being set to "L" level, the hardware doesn't stand by. However the HST pin becomes available after the reset cancellation, the HST pin must once be back to "H" level. *Power on Reset Make sure to make power on reset at turning on the power supply or returning on the power supply when the power supply voltage is below the warranty range for normal operation.

2. Registers
The FR family has two types of registers; dedicated registers embedded on the CPU and general-purpose registers on memory. *Dedicated registers Program counter (PC) Program status (PS) : 32-bit length, indicates the location of the instruction to be executed. : 32-bit length, register for storing register pointer or condition codes. : Holds top address of vector table used in EIT (Exceptional/Interrupt/ Table base register (TBR) Trap processing. Return pointer (RP) : Holds address to resume operation after returning from a subroutine. System stack pointer (SSP) : Indicates system stack space. User's stack pointer (USP) : Indicates user's stack space. Multiplication/division result : 32-bit length, register for multiplication/division. register (MDH/MDL)

N-flag : Indicates sign bit when division result is assumed to be in the 2's complement format. Z-flag : Indicates whether or not the result of division was "0". : Assumes the operand used in calculation in the 2's complement format and indicates whether or V-flag not overflow has occurred. C-flag : Indicates if a carry or borrow from the MSB has occurred. *System condition code register (SCR) T-flag : Specifies whether or not to enable step trace trap. *Interrupt level mask register (ILM) ILM4 to ILM0 : Register for holding interrupt level mask value. The value held by this register is used as a level mask. When an interrupt request issued to the CPU is higher than the level held by ILM, the interrupt request is accepted.

s GENERAL-PURPOSE REGISTERS
R0 to R15 are general-purpose registers embedded on the CPU. These registers functions as an accumulator and a memory access pointer.
32 bit R0 R1 : R12 R13 R14 R15 :
AC FP SP
Initial value XXXX XXXXH : : : : : : XXXX XXXXH 00 0 0 0 0 0 0H
Of the above 16 registers, following registers have special functions. To support the special functions, part of the instruction set has been sophisticated to have enhanced functions. R13: Virtual accumulator (AC) R14: Frame pointer (FP) R15: Stack pointer (SP) Upon reset, values in R0 to R14 are not fixed. Value in R15 is initialized to be 0000 0000H (SSP value).

5. PWM Timer
The PWM timer can output high accurate PWM waves efficiently. MB91101 has inner 4-channel PWM timers, and has the following features. * Each channel consists of a 16-bit down counter, a 16-bit data resister with a buffer for cycle setting, a 16-bit compare resister with a buffer for duty setting, and a pin controller. * The count clock of a 16-bit down counter can be selected from the following four inner clocks. * Inner clock , /4, /16, /64 * The counter value can be initialized "FFFFH" by the resetting or the counter borrow. * PWM output (each channel) * Resister description Cycle setting register: Reload data register with a buffer Duty factor setting register: Compare register with a buffer Transfer from the buffers uses the counter borrow method. * Pin control outline Set to '1' at a duty factor match. (Preferential) Set to '0' at a counter borrow. The output value fixed mode is available, which makes all 'L' (or 'H') output easy. The polarity can also be specified. * Interrupt requests can be generated by selected a combination of events: This timer is activated. A counter borrow is generated (cycle match). A duty factor match is generated. A counter borrow is generated (cycle match) or a duty factor match is generated. DMA transfer can be invoked by the above interrupt request. * Simultaneous activation of multiple channels of the PWM timer can be set by software or by using another interval timer. Restarting the PWM timer during operation can also be set.
