Function

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

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

G

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.

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 hold function disabled.

G Hold request input pin. This function is enabled when both the external bus

and the hold function are enabled.

Wave form output pin for output compare OCU4

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 hold function disabled.

G Hold acknowledge output pin. This function is enabled when both the

external bus and the hold function are enabled.

Wave form output pin for output compare OCU5

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 external ready function disabled.

G Ready input pin. This function is enabled when both the external bus and

the external ready function are enabled.

Wave form output pin for output compare OCU6
