APFCON Register

(PIC12F615/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.
