Function

117 to 120

P24 to P27

This is a general purpose I/O port. When the bits of external address

output control register (HACR) are set to “1” in external bus mode, these

pins function as general purpose I/O ports.

A20 to A23

When the bits of external address output control register (HACR) are set

to “0” in multiplex mode, these pins function as address high output pins.

When the bits of external address output control register (HACR) are set

to “0” in non-multiplex mode, these pins function as address high output

pins.

PPG0 to PPG3

Function as ch.0 to ch.3 output pins for the 8-bit PPG timer.

P30

General purpose input/output port.

A00

Function as the external address pin in non-multi-bus mode.

TIN1

Function as an event input pin for 16-bit reload timer ch.1.

P31

General purpose input/output port.

A01

Function as the external address pin in non-multi-bus mode.

TOT1

Function as the output pin for 16-bit reload timer ch.1.

P32

General purpose input/output port.

A02

Function as the external address pin in non-multi-bus mode.

TIN2

Function as an event input pin for 16-bit reload timer ch.2.

P33

General purpose input/output port.

A03

Function as the external address pin in non-multi-bus mode.

TOT2

Function as the output pin for 16-bit reload timer ch.2.

5 to 8

P34 to P37

General purpose input/output port.

A04 to A07

Function as the external address pin in non-multi-bus mode.

P40

General purpose input/output port.

A08

Function as the external address pin in non-multi-bus mode.

TIN0

Function as an event input pin for 16-bit reload timer ch.0.

P41

General purpose input/output port.

A09

Function as the external address pin in non-multi-bus mode.

TOT0

Function as the output pin for 16-bit reload timer ch.0.

P42

General purpose input/output port.

A10

Function as the external address pin in non-multi-bus mode.

SIN0

Function as a data input pin for UART ch.0.

P43

General purpose input/output port.

A11

Function as the external address pin in non-multi-bus mode.

SOT0

Function as a data output pin for UART ch.0.

P44

General purpose input/output port.

A12

Function as the external address pin in non-multi-bus mode.

SCK0

Function as a clock I/O pin for UART ch.0.
