These eight 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.
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.
These eight I/O lines comprise port C. All port C lines are configured as
input during power-on or reset. Port C has pullup devices and interrupt
capability by pin; however, the state of any pin is determined by the user
at the time of code submission. For a detailed description of I/O
programming, refer to
shared with the output of the pulse-width modulation (PWM) function.
These seven port lines comprise port D. The state of any pin is software
programmable and the lines are configured as input during power-on or
reset. PD4 and PD5 are shared with the SSI subsystem, PD6 is shared
with the 16-bit timer subsystem, and PD0–PD3 are shared with the
comparators. For a detailed description on I/O programming, refer to
7.7 Input/Output Port Pin
This pin is used for the16-bit timer input capture operation. Depending
on the value of the IEDG bit in the timer control register (TCR), the
appropriate level of transition on TCAP will be monitored. When the
