A8–A15
P0.0–P0.7
Nibble programmable port; input or output
mode selected by software; Schmitt trigger
input or push-pull, open-drain output with
software assignable pull-ups; alternately
configurable as external interface address
lines A8–A15
Same general characteristics as port 0;
alternately configurable as external interface
address/data lines AD0–AD7; high current
drive capability (15-mA typical value)
General I/O port with Schmitt trigger input or
push-pull output; bit programmable:
P2.0 / address strobe (
