PIC16F677T-ESS

20-Pin Flash-Based, 8-Bit CMOS Microcontrollers with nanoWatt Technology

Microchip 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.
