99 to 2
1 to 4
P24 to P27
G
General purpose I/O ports
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.
A20 to A23
A20 to A23 for output pins of the external address/data
bus. When the corresponding bit in the external address
output control register (HACR) is 0, the pins are enabled as
high address output pins (A20 to A23).
IN0 to IN3
Data sample input pins for input capture ICU0 to ICU3.
35
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 the external bus is enabled.
IN4
Data sample input pin for input capture ICU4.
46
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
External read strobe output pin for data bus. This function
is enabled when the external bus is enabled.
IN5
Data sample input pin for input capture ICU5.
57
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 when the WR/WRL pin output is disabled.
WRL/
WR
Write strobe output pin for the external 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
while WR is used to write-strobe 8 bits of the data bus in
8-bit access.
INT10R
External interrupt request input pin (Sub) for INT10.
68
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 or when
the WRH pin output is disabled.
WRH
Write strobe output pin for the upper 8 bits of the external
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.
