Functions

(Port G)

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

up resistor can be set through the software in a unit of 4 bits.

(8 pins)

(Port H)

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

up resistor can be set through the software in a unit of 4 bits.

(8 pins)

(Port I)

8-bit I/O port. I/O can be

set in a unit of single

bits. Incorporation of

pull-up resistor can be

set through the software

in a unit of 4 bits.

(8 pins)

External interruption request inputs.

(5 pins)

Serial clock I/O. (CH2)

Serial data input. (CH2)

Serial data output. (CH2)

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. For usage

as event counter, input to TEX, and open TX.

Low-level active, system reset.

NC.

Under normal operating conditions, connect to VDD.

Reference voltage input for A/D converter.

A/D converter GND.

Positive power supply.

GND.
