PIC16F631_08 Datasheet, PDF (80/306 Pages) Microchip Technology – 20-Pin Flash-Based, 8-Bit CMOS Microcontrollers with nanoWatt Technology

PIC16F631/677/685/687/689/690
4.5.5 RC4/C2OUT/P1B
The RC4/C2OUT/P1B^{(1, 2)} is configurable to function
as one of the following:
• a general purpose I/O
• a digital output from Comparator C2
• a PWM output
Note 1: Enabling both C2OUT and P1B will cause
a conflict on RC4 and create unpredictable
results. Therefore, if C2OUT is enabled,
the ECCP+ can not be used in Half-Bridge
or Full-Bridge mode and vise-versa.
2: P1B is available on
PIC16F685/PIC16F690 only.

4.5.6 RC5/CCP1/P1A
The RC5/CCP1/P1A⁽¹⁾ is configurable to function as
one of the following:
• a general purpose I/O
• a digital input/output for the Enhanced CCP
• a PWM output
Note 1: CCP1 and P1A are available on
PIC16F685/PIC16F690 only.
