PORT0
[7:0]
I/O Port0 is an 8-bit bi-directional I/O port.
In accesses to external memory, port0 outputs the low
byte of the external memory address,
time-multiplexed with the data byte being written or
read.
SAD[7:0]: low byte address
and data bus, bi-directional.
SA[7:0]/GP
A[15:8]
I/OSA[7:0]: lower address byte for external program and
data memories, latched by ALE from Port0 address
phase, output. This is the default. Optionally these
pins can be used as general purpose IO signals.
GPA[15:8]: general purpose IO bus A bits[15:8],
bi-directional.
LATS=1, SA[7:0]: low byte
address bus, input.
LATS=0, SA[7:0] output or
GPA[15:8] selected by register
PORT2
[7:0]
I/O Port2 is an 8-bit bi-directional I/O port with internal
pull-up. Port2 also serves as memory address bus.
In accesses to external memory, port2 outputs the
high byte of the external memory address.
SA[15:8]: high byte address
bus, input.
PORT1
[7:0]
I/O Port1 is an 8-bit bi-directional I/O port with internal
pull-up.
P1.0 and p1.1 also serve the T2 and T2EX functions,
respectively.
P1.2 and P1.3 also serve the RXD2 and TXD2,
respectively.
P1.4: GPA7, general purpose IO bus A bit 7, initial in
input state
P1.5, P1.6 and P1.7 also serve external interrupt
inputs
P1.4: INTS#, output

I/O Port3 is an 8-bit bi-directional I/O port with internal
pull-up.
Port3 also serve following special functions:
P3.0 RXD1(serial input port)
P3.1 TXD1(serial output port)
P3.2 IR input connecting to IR receiver
P3.3: GPA6, general purpose IO bus A bit 6, initial in
input state
P3.4 T0 (timer 0 external input)
P3.5 T1 (timer 1 external input)
P3.6 WR# (external data memory write)
P3.7 RD# (external data memory read)
P3.3: INTM#, output
P3.6: WR#, input
P3.7: RD#, input
PORT4
[7:0]
I/OPort4 is an 8-bit bi-directional I/O port with internal
pull-up. It can be used for bank selection of external
program and data memories, internally latched with
ALE.
PORT5
[7:0]
I/OPort5 is an 8-bit bi-directional I/O port, default in
input state.
FWR# OFlash write enable output
4.2.1 External Micro-controller Mode
