PIC16(L)F1454/5/9
12.1 Alternate Pin Function
The Alternate Pin Function Control register is used to
steer specific peripheral input and output functions
between different pins. The APFCON register is shown
in Register 12-1. For this device family, the following
functions can be moved between different pins.
• CLKR
• SDO
• SS
• T1G
• P2
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.

SSSEL: Pin Selection bit
For 14-Pin Devices (PIC16(L)F1454/5):
1 = SS function is on RA3
0 = SS function is on RC3
For 20-Pin Devices (PIC16(L)F1455/9):
1 = SS function is on RA3
