Pull-up enabled only with external MCLR Configuration.
RC1 is the default pin location for CCP2. RB3 may be selected by changing the CCP2SEL bit in the APFCON register.
RA5 is the default pin location for SS. RA0 may be selected by changing the SSSEL bit in the APFCON register.
PIC16F724/727/PIC16LF724/727 devices only.
Note:
The PIC16F722/3/4/6/7 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 PIC16LF722/3/4/6/7 devices do not have the
voltage regulator and therefore no external capacitor is required.
