Description

(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 ports. 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.

External interruption

request inputs.

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 circuit.

Connect a 32kHz crystal oscillator between TEX and TX.

For usage as event input, connect clock oscillation source 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.
