PIC12(L)F1822/16(L)F1823
12.1 Alternate Pin Function
The Alternate Pin Function Control (APFCON)
registers are used to steer specific peripheral input and
output functions between different pins. The APFCON
registers are shown in Register 12-1. For this device
family, the following functions can be moved between
different pins.
•RX/DT
•TX/CK
•SDO
•SS
(Slave Select)
•T1G
•P1B
• CCP1/P1A
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.
