Function

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

register (HACR) is 1.

G 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.

Data sample input pin for input capture ICU0

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

register (HACR) is 1.

G 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.

Data sample input pin for input capture ICU1

Trigger input pin for A/D converter

General purpose I/O port

H Serial data I/O pin for I2C 0

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

General purpose I/O port

H Serial clock I/O pin for I2C 0

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

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.

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

Data sample input pin for input capture ICU4

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.

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

enabled.

Data sample input pin for input capture ICU5

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.

G

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.

External interrupt request input pin for INT10

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

G

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

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.
