PIC16F193X/LF193X
6.1
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
