2.2.2.7 APFCON Register
(PIC12F615/617/HV615 only)
The Alternate Pin Function Control (APFCON) register
is used to steer specific peripheral input and output
functions between different pins. For this device, the
P1A, P1B and Timer1 Gate functions can be moved
between different pins.
The APFCON register bits are shown in Register 2-7.
