PIC16(L)F722A/723A
6.0 I/O PORTS
There are as many as thirty-five general purpose I/O
pins available. Depending on which peripherals are
enabled, some or all of the pins may not be available as
general purpose I/O. In general, when a peripheral is
enabled, the associated pin may not be used as a
general purpose I/O pin.
6.1 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 6-1. For this device family, the
following functions can be moved between different
pins:
•SS
(Slave Select)
• CCP2

Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-2 Unimplemented: Read as ‘0’.
bit 1 SSSEL: SS
Input Pin Selection bit
0 =SS function is on RA5/AN4/CPS7/SS/VCAP
1 =SS function is on RA0/AN0/SS/VCAP
bit 0 CCP2SEL: CCP2 Input/Output Pin Selection bit
0 = CCP2 function is on RC1/T1OSI/CCP2
1 = CCP2 function is on RB3/CCP2
