(Port H)

8-bit I/O port. I/O can be set in a unit of single bit.

(8 pins)

(Port I)

8-bit output ports.

FDP segment signal outputs.

(8 bits)

Outputs for FDP timing (digit) signals/segment signals.

FDP timing signal outputs.

FDP voltage supply when incorporated resistor is set by mask option.

Crystal connectors for system clock oscillation. When the clock is supplied

externally, input to EXTAL; opposite phase clock should be input to XTAL.

Crystal connectors for 32kHz timer/counter clock oscillation. Set 32kHz

crystal oscillator between TEX and TX. For usage as event input, attach

clock source to TEX, and open TX.

Low-level active, system reset.

NC.

Under normal operation, connect to VDD.

Reference voltage input for A/D converter.

A/D converter GND.

Positive power supply.

GND.
