1 to 4
99 to 2
P24 to P27
G
General-purpose I/O pins. It is possible to select whether or not a
pull-up resistance is used by configuring a register. In external
bus mode, each 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
External address bus output pins. When the corresponding bits in
the external address output control register (HACR) are 0, the
pins are enabled as high address output pins (A20 to A23).
IN0 to IN3
Trigger input pins for input captures 0 to 3.
53
P30
G
General-purpose I/O pin. It is possible to select whether or not a
pull-up resistance is used by configuring a register. 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
Trigger input pin for input capture 4.
64
P31
G
General-purpose I/O pin. It is possible to select whether or not a
pull-up resistance is used by configuring a register. This function
is enabled in single-chip mode.
RD
External read strobe output pin. This function is enabled when the
external bus is enabled.
IN5
Trigger input pin for input capture 5.
75
P32
G
General-purpose I/O pin. It is possible to select whether or not a
pull-up resistance is used by configuring a register. This function
is enabled either in single-chip mode or when the WR/WRL pin
output disabled.
WR / WRL
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 as a write strobe output for the lower 8
bits of the data bus in 16-bit access while WR is used as the write
strobe for the 8 bits of the data bus in 8-bit access.
INT10R
External interrupt request input pin (sub) .
86
P33
G
General-purpose I/O pin. It is possible to select whether or not a
pull-up resistance is used by configuring a register. This function
is enabled either in single-chip mode or when the WRH pin output
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,
and the external bus is in 16-bit mode, and the WRH output pin is
enabled.
