Functions
A8–A15
I/O port with nibble-programmable pins;
schmitt trigger input or push-pull, open-drain
output and software assignable pull-up; also
configurable as external interface address lines
A8–A15.
35–28
P1.0–P1.7
I/O
Same general characteristics as port 0; also
configurable as external interface address/data
lines AD0–AD7.

43–36
AD0–AD7
P2.0–P2.3
I/O
I/O port with bit-programmable pins; schmitt
trigger input or push-pull output and software
assignable pull-ups. Lower nibble pins 0–3 are
configurable for external interface signals.
