Note 1: Pull-up enabled only with external MCLR configuration.

2: RC1 is the default pin location for CCP2. RB3 may be selected by changing the CCP2SEL bit in the APFCON register.

3: RA5 is the default pin location for SS

. RA0 may be selected by changing the SSSEL bit in the APFCON register.

4: PIC16F722A/723A devices only.

Note: The PIC16F722A/723A devices have an internal low dropout voltage regulator. An external capacitor must

be connected to one of the available V

CAP pins to stabilize the regulator. For more information, see

Section 5.0 “Low Dropout (LDO) Voltage Regulator”. The PIC16LF722A/723A devices do not have the

voltage regulator and therefore no external capacitor is required.
