Function
54
P30
G
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
55
P31
G
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.
RD
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
56
P32
G
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
57
P33
G
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.
58
P34
G
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.
HRQ
Hold request input pin. This function is enabled when both the external bus
and the hold function are enabled.
OUT4
Wave form output pin for output compare OCU4
59
P35
G
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.
HAK
Hold acknowledge output pin. This function is enabled when both the
external bus and the hold function are enabled.
OUT5
Wave form output pin for output compare OCU5
60
P36
G
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.
RDY
Ready input pin. This function is enabled when both the external bus and
the external ready function are enabled.
OUT6
Wave form output pin for output compare OCU6
