RC5/CCP1/P1A
The RC4/C2OUT/P1B(1, 2) is configurable to function
as one of the following:
The RC5/CCP1/P1A(1) is configurable to function as
one of the following:
• a general purpose I/O
• a digital output from Comparator C2
• a PWM output
• a general purpose I/O
• a digital input/output for the Enhanced CCP
• 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.
Note 1: CCP1 and P1A are available on
PIC16F685/PIC16F690 only.
