I/O
Description
I/O
PG0 to PG2
(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.
(3 pins)
I/O/Input

PI3/INT3
I/O
PI4 to PI6
Input
Crystal connectors for system clock oscillation. When the clock is supplied
externally, input to EXTAL; opposite phase clock should be input to XTAL.
