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 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
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 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.
Waveform 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.
Waveform 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.
Waveform output pin for output compare OCU6.
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 CLK output disabled.
G CLK output pin. This function is enabled when both the external bus and
CLK output are enabled.
Waveform output pin for output compare OCU7.
