85 to 92
P00 to P07
H
General I/O port with programmable pullup. This function is en-
abled in the single-chip mode.
AD00 to AD07
I/O pins for 8 lower bits of the external address/data bus. This func-
tion is enabled when the external bus is enabled.
93 to 100
P10 to P17
H
General I/O port with programmable pullup. This function is en-
abled in the single-chip mode.
AD08 to AD15
I/O pins for 8 higher bits of the external address/data bus. This func-
tion is enabled when the external bus is enabled.
1 to 8
P20 to P27
H
General I/O port with programmable pullup. This function is en-
abled in the single-chip mode.
A16 to A23
I/O pins of 8 bits for A16 to A23 ot the external address bus. This
function is enabled when the external bus is enabled.
9
P30
H
General I/O port with programmable pullup. This function is en-
abled in the single-chip mode.
ALE
Address latch enable output pin. This function is enabled when the
external bus is enabled.
10
P31
H
General I/O port with programmable pullup. This function is en-
abled in the single-chip mode.
RD
Read strobe output pin for the data bus. This function is enabled
when the external bus is enabled.
12
P32
H
General I/O port with programmable pullup. This function is en-
abled 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 the external bus is in enable mode and the WR/WRL pin out-
put is enabled. WRL is used as a write-strobe output pin for 8 lower
bits of the data bus in 16-bit access while WR is used as a write-
strobe output pin for 8 bits of the data bus in 8-bit access.
WR
13
P33
H
General I/O port with programmable pullup. This function is en-
abled in the single-chip mode or external bus 8-bit mode or when
WRH pin output is 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 ex-
ternal bus 16-bit mode is selected, and when the WRH output pin
is enabled.
