These eight input/output (I/O) lines comprise port A. The state of any pin
is software programmable and all port A lines are configured as input
during power-on or reset. For detailed information on I/O programming,
see
These eight I/O lines comprise port B. The state of any pin is software
programmable, and all port B lines are configured as input during power-
on or reset. Port B has mask option enabled pullup devices and interrupt
capability by pin. The interrupts and pullups are enabled together. For a
detailed description on I/O programming, refer to
Programming.
These eight I/O lines comprise port C. The state of any pin is software
programmable and all port C lines are configured as input during power-
on or reset. PC7 has high current sink and source capability. For a
detailed description on I/O programming, refer to
Programming.
These seven port lines comprise port D. PD7 and PD5–PD0 are input
only. PD0 and PD1 are shared with the SCI subsystem and PD2–PD5
are shared with the SPI subsystem. For a detailed description on I/O
