83 to 90
85 to 92
P00 to P07
I
General I/O port with programmable pull-up. This function is
enabled in the single-chip mode.
AD00 to AD07
I/O pins for 8 lower bits of the external address/data bus. This
function is enabled when the external bus is enabled.
91 to 98 93 to 100
P10 to P17
I
General I/O port with programmable pull-up. This function is
enabled in the single-chip mode.
AD08 to AD15
I/O pins for 8 higher bits of the external address/data bus. This
function is enabled when the external bus is enabled.
99 to 6
1 to 8
P20 to P27
I
General I/O port with programmable pull-up. In external bus
mode, this function is valid when the corresponding bits in the
external address output control register (HACR) are set to “1”.
A16 to A23
8-bit output pins for A16 to A23 at the external address bus. In
external bus mode, this function is valid when the correspond-
ing bits in the external address output control register (HACR)
are set to “0”.

P30
I
General I/O port with programmable pull-up. This function is
enabled in the single-chip mode.
ALE
Address latch enable output pin. This function is enabled
when the external bus is enabled.

P31
I
General I/O port with programmable pull-up. This function is
enabled in the single-chip mode.
RD
Read strobe output pin for the data bus. This function is
enabled when the external bus is enabled.

P32
I
General I/O port with programmable pull-up. This function is
enabled in the single-chip mode or when the WR/WRL pin
output is disabled.
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 write-strobe output pin for the
lower 8 bits of the data bus in 16-bit access. WR is write-strobe
output pin for the 8 bits of the data bus in 8-bit access.
