11.1

Alternate Pin Function

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 11-1. For this device family, the

following functions can be moved between different

pins.

•SS

•T1G

•CLC1

• NCO1

These bits have no effect on the values of any TRIS

correct pin. The unselected pin will be unaffected.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-5

Unimplemented: Read as ‘0’
