11.1 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 11-1. For this device family, the
following functions can be moved between different
pins.
•RX/DT
•TX/CK
• CWGOUTA
• CWGOUTB
•PWM2
•PWM1
These bits have no effect on the values of any TRISx
register. PORTx and TRISx overrides will be routed to
the correct pin. The unselected pin will be unaffected.
