Function

General-purpose I/O port

This port is available in the single-chip mode or when the middle

address control register setting is “port”, with the 8-bit PPG

output is disabled.

Output pin for external address bus A09

This pin is available in an external-bus mode and when the middle

address control register setting is “address.”

PPG timer output pin

This pin is available when the PPG operation mode control

register specification is the PPG output pin.

General-purpose I/O ports

These ports are available in the single-chip mode or when the

middle address control register setting is “port”, with the 16-bit

reload timer 1 (ch.0 to ch.3) output is disabled.

Output pins for external address buses A10 to A13

These pins are available in an external-bus mode and when the

middle address control register setting is “address.”

16-bit reload timer 1 (ch.0 to ch.3) output pin

These pins are available when the 16-bit reload timer 1 (ch.0 to

ch.3) is output operation.

General-purpose I/O port

This port is available when the UART (ch.2) clock output is

disabled either in the single-chip mode or when the middle

address control register setting is “port.”

Output pin for external address bus A14

This pin is available when the UART (ch.2) clock output is

disabled in an external-bus mode and when the middle address

control register setting is “address.”

UART (ch.2) clock output pin (SCK3)

This pin is available when the UART (ch.2) clock output is

enabled.

UART (ch.2) external clock input pin (SCK3)

This pin is available when the port is in input mode and the UART

(ch.2) specification is external clock mode.

General-purpose I/O port

This port is available in the single-chip mode or when the middle

address control register setting is “port.”

Output pin for external address bus A15

This pin is available in an external-bus mode and when middle

address control register setting is “address.”

UART (ch.2) serial data input pin (SID3)

Since this input is used whenever the SID3 is in input operation,

the output by any other function must be suspended unless the

output is intentionally performed.
