I/O PORTS
There are thirty-five general purpose I/O pins available.
Depending on which peripherals are enabled, some or
all of the pins may not be available as general purpose
I/O. In general, when a peripheral is enabled, the
associated pin may not be used as a general purpose
I/O pin.
Each port has two registers for its operation. These
registers are:
TRISx registers (data direction register)
PORTx registers (port read/write register)
Ports with analog functions also have an ANSELx
register which can disable the digital input and save
power. A simplified model of a generic I/O port, without
the interfaces to other peripherals, is shown in
FIGURE 6-1:

OPERATION

Alternate Pin Function
The Alternate Pin Function Control (APFCON) register
is used to steer specific peripheral input and output
functions between different pins. The APFCON register
is shown in Register 6-1. For this device family, the
following functions can be moved between different
pins.
