Function

LQFP64*

P24

General purpose I/O port. The register can be set to select whether to use a pull-up

resistor. In external bus mode, the pin is enabled as a general-

purpose I/O port when the corresponding bit in the external address output control

A20

Output pin for A20 of the external address data bus. When the corresponding bit in the

external address output control register (HACR) is 0, the pin is

enabled as high address output pin A20.

IN0

Data sample input pin for input capture ICU0

P25

General purpose I/O port. The register can be set to select whether to use a pull-up

resistor. In external bus mode, the pin is enabled as a general-

purpose I/O port when the corresponding bit in the external address output control

A21

Output pin for A21 of the external address data bus. When the corresponding bit in the

external address output control register (HACR) is 0, the pin is enabled as high address

output pin A21.

IN1

Data sample input pin for input capture ICU1

ADTG

Trigger input pin for A/D converter

P44

General purpose I/O port

SDA0

Serial data I/O pin for I2C 0

FRCK0

Input pin for the 16-bit I/O Timer 0

P45

General purpose I/O port

SCL0

Serial clock I/O pin for I2C 0

FRCK1

Input pin for the 16-bit I/O Timer 1

P30

General purpose I/O port. The register can be set to select whether to use a pull-up

resistor. This function is enabled in single-chip mode.

ALE

Address latch enable output pin. This function is enabled when external bus is enabled.

IN4

Data sample input pin for input capture ICU4

P31

General purpose I/O port. The register can be set to select whether to use a pull-up

resistor. This function is enabled in single-chip mode.

Read strobe output pin for data bus. This function is enabled when external bus is

enabled.

IN5

Data sample input pin for input capture ICU5

P32

General purpose I/O port. The register can be set to select whether to use a pull-up

resistor. This function is enabled either in single-chip mode or with the WR/WRL pin

output disabled.

WR/WRL

Write strobe output pin for the data bus. This function is enabled when both the external

bus and the WR/WRL pin output are enabled. WRL is used to write-strobe 8 lower bits

of the data bus in 16-bit access. WR is used to write-strobe 8 bits of the data bus in 8-bit

access.

INT10R

External interrupt request input pin for INT10

P33

General purpose I/O port. The register can be set to select whether to use a pull-up

resistor. This function is enabled either in single-chip mode, in

external bus 8-bit mode or with the WRH pin output disabled.

WRH

Write strobe output pin for the 8 higher bits of the data bus. This function is enabled when

the external bus is enabled, when the external bus 16-bit mode is selected, and when

the WRH output pin is enabled.
