PIC16F193X/LF193X
6.1 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 6-1. For this device family, the
following functions can be moved between different
pins.
• SS (Slave Select)
• CCP2
• CCP3
• Timer1 Gate
• SR Latch SRNQ output
• Comparator C2 output
These bits have no effect on the values of any TRIS
register. PORT and TRIS overrides will be routed to the
correct pin. The unselected pin will be unaffected.
