Handling Devices Do Not Exceed Maximum Rating (preventing “latch up”) ■ On a CMOS IC, latch-up may occur when applying a voltage higher than Vcc or a voltage lower than Vss to input or output pin, which has no middle or high withstand voltage. Latch-up may also occur when a voltage exceeding maximum rating is applied across Vcc pin and Vss pin. ■ Latch-up causes drastic increase of power current, which may lead to destruction of elements by heat. Extreme caution must be taken not to exceed maximum rating. ■ When turning on and off analog power source, take extra care not to apply an analog power voltages (AVcc and AVR) and analog input voltage that are higher than digital power voltage (Vcc). Handling Unused Pins ■ Leaving unused input pins open may cause permanent destruction by malfunction or latch-up. Apply pull-up or pull-down process to the unused pins using resistors of 2 k or higher. Leave unused input/output pins open under output status, or process as input pins if they are under input status. Using External Clock ■ When using an external clock, drive only X0 pin and leave X1 pin open. An example of using an external clock is shown below.  Using external clock X0 Open X1 MB90385 series Document Number: 002-07765 Rev. *A Page 10 of 81 MB90387/387S/F387/F387S MB90V495G Notes When Using No Sub Clock ■ If an oscillator is not connected to X0A and X1A pin, apply pull-down resistor to X0A pin and leave X1A pin open. About Power Supply Pins ■ If two or more Vcc and Vss pins exist, the pins that should be at the same potential are connected to each other inside the device. For reducing unwanted emissions and preventing malfunction of strobe signals caused by increase of ground level, however, be sure to connect the Vcc and Vss pins to the power source and the ground externally. ■ Pay attention to connect a power supply to Vcc and Vss of MB90385 series device in a lowest-possible impedance. ■ Near pins of MB90385 series device, connecting a bypass capacitor is recommended at 0.1 F across Vcc pin and Vss pin. Crystal Oscillator Circuit ■ Noises around X0 and X1 pins cause malfunctions on a MB90385 series device. Design a print circuit so that X0 and X1 pins, an crystal oscillator (or a ceramic oscillator), and bypass capacitor to the ground become as close as possible to each other. Furthermore, avoid wires to X0 and X1 pins crossing each other as much as possible. ■ Print circuit designing that surrounds X0 and X1 pins with grounding wires, which ensures stable operation, is strongly recommended. Caution on Operations during 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. Sequence of Turning on Power of A/D Converter and Applying Analog Input ■ Be sure to turn on digital power (Vcc) before applying signals to the A/D converter and applying analog input signals (AN0 to AN7 pins). ■ Be sure to turn off the power of A/D converter and analog input before turning off the digital power source. ■ Be sure not to apply AVR exceeding AVcc when turning on and off. (No problems occur if analog and digital power is turned on and off simultaneously.) Handling Pins When A/D Converter is Not Used ■ If the A/D converter is not used, connect the pins under the following conditions: “AVcc=AVR=Vcc,” and “AVss=Vss” Note on Turning on Power ■ For preventing malfunctions on built-in step-down circuit, maintain a minimum of 50 s of voltage rising time (between 0.2 V and 2.7V) when turning on the power. Stabilization of Supply Voltage ■ A sudden change in the supply voltage may cause the device to malfunction even within the specified VCC supply voltage operating range. Therefore, the VCC supply voltage should be stabilized. For reference, the supply voltage should be controlled so that VCC ripple variations (peak-to-peak values) at commercial frequencies (50 Hz / 60 Hz) fall below 10 of the standard VCC supply voltage and the coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.

Note: When internal ROM is operating, F2MC-16LX allows viewing ROM data image on FF bank at upper-level of 00 bank. This function is called “mirroring ROM,” which allows effective use of C compiler small model. F2MC-16LX assigns the same low order 16-bit address to FF bank and 00 bank, which allows referencing table in ROM without specifying “far” using pointer. For example, when accessing to “00C000H”, ROM data at “FFC000H” is accessed actually. However, because ROM area of FF bank exceeds 48 Kbytes, viewing all areas is not possible on 00 bank image. Because ROM data of “FF4000H” to “FFFFFFH” is viewed on “004000H” to “00FFFFH” image, store a ROM data table in area “FF4000H” to “FFFFFFH.” Document Number: 002-07765 Rev. *A Page 13 of 81 MB90387/387S/F387/F387S MB90V495G 10.

Peripheral Resources 12.1 I/O Ports The I/O ports are used as general-purpose input/output ports (parallel I/O ports). The MB60385 series model is provided with 5 ports (34 inputs). The ports function as input/output pins for peripheral functions also. I/O Port Functions An I/O port, using port data resister (PDR), outputs the output data to I/O pin and input a signal input to I/O port. The port direction register (DDR) specifies direction of input/output of I/O pins on a bit-by-bit basis. The following summarizes functions of the ports and sharing peripheral functions: ■ Port 1: General-purpose input/output port, used also for PPG timer output and input capture inputs. ■ Port 2: General-purpose input/output port, used also for reload timer input/output and external interrupt input. ■ Port 3: General-purpose input/output port, used also for A/D converter activation trigger pin. ■ Port 4: General-purpose input/output port, used also for UART input/output and CAN controller send/receive pin. ■ Port 5: General-purpose input/output port, used also analog input pin.

Interval Timer Function ■ When the counter of time-base timer reaches an interval time specified by interval time selection bit (TBTC:TBC1, TBC0), an overflow (carrying-over) occurs (TBTC: TBOF=1) and interrupt request is generated. ■ If an interrupt by overflow is permitted (TBTC: TBIE=1), an interrupt is generated when overflow occurs (TBTC: TBOF=1). ■ The following four interval time settings are selectable: Interval Time of Time-base Timer Count Clock 2/HCLK (0.5 s) Interval Time 12 2 /HCLK (Approx. 1.0 ms) 214/HCLK (Approx. 4.1 ms) 216/HCLK (Approx. 16.4 ms) 219/HCLK (Approx. 131.1 ms) HCLK: Oscillation clock Values in parentheses “( )” are those under operation of 4-MHz oscillation clock.

If the counter is not cleared within an interval time, CPU is reset. Watchdog Timer Functions ■ The watchdog timer is a timer counter that prevents runaway of a program. Once a watchdog timer is activated, the counter of watchdog timer must always be cleared within a specified time of interval. If specified interval time elapses without clearing the counter of a watchdog timer, CPU resetting occurs. This is the function of a watchdog timer. ■ The interval time of a watchdog timer is determined by a clock cycle, which is input as a count clock. Watchdog resetting occurs between a minimum time and a maximum time specified. ■ The output target of a clock source is specified by the watchdog clock selection bit (WTC: WDCS) in the watch timer control register. ■ Interval time of a watchdog timer is specified by the time-base timer output selection bit / watch timer output selection bit (WDTC: WT1, WT0) in the watchdog timer control register. Interval Timer of Watchdog Timer Min Max Clock Cycle Min Max Clock Cycle Approx. 3.58 ms Approx. 4.61 ms (2 2 ) /HCLK Approx. 0.457 s Approx. 0.576 s (21229) /SCLK Approx. 14.33 ms Approx. 18.3 ms (216213) /HCLK Approx. 3.584 s Approx. 4.608 s (215212) /SCLK Approx. 57.23 ms Approx. 73.73 ms (218215) /HCLK Approx. 7.168 s Approx. 9.216 s (216213) /SCLK Approx. 458.75 ms Approx. 589.82 ms (221218) /HCLK Approx. 14.336 s Approx. 18.432 s (217214) /SCLK 14 11 HCLK: Oscillation clock (4 MHz), CSCLK: Sub clock (8.192 kHz) Notes: ■ If the time-base timer is cleared when watchdog timer count clock is used as time base timer output (carry-over signal), watchdog reset time may become longer. ■ When using the sub clock as machine clock, be sure to specify watchdog timer clock source selection bit (WDCS) in watch timer control register (WTC) at “0,” selecting output of watch timer.

If the addresses match with each other, an instruction to be processed next in program is forcibly replaced with INT9 instruction, and process branches to the interrupt process program. Using INT9 interrupt, this function is available for correcting program by batch processing. Address Matching Detection Function Outline ■ An address of an instruction to be processed next to a currently-processed instruction of the program is always retained in an address latch via internal data bus. By the address matching detection function, the address value retained in the address latch is always compared with an address specified in detection address setting register.
