5.1

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 5-1. For this device family, the

following functions can be moved between different

pins.

•Timer1 Gate

• COG1

These bits have no effect on the values of any TRIS

correct pin. The unselected pin will be unaffected.

bit 7

bit 0

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’.

bit 4

T1GSEL: Timer 1 Gate Input Pin Selection bit

= T1G function is on RA3

= T1G function is on RA4

bit 3-0

Unimplemented: Read as ‘0’.
