16F876 - 2PWM pins with 32768KHz crystal on Timer1

Hi there,

I need to use the two PWM modules of PIC16F876, but I also need to use a 32,768Khz crystal, driving a clock based on TIMER 1. Is possible to change CCP2 pin to another pin, leaving RC1 (T1OSI) free?

Regards.

Use a similar but more modern PIC: 16F767. It has the CCP2B3 fuse
setting. It can switch the CCP2 output to Pin B3 instead. This will solve
your problem.

This is a start, but I will try to do for software first. Using 16f767 will add another part number in my stock list, i am tryng to avoid this. In fact, if i could find one small 8 pin DIL, 2 or 3W mono audio amplifier, i could use I2C to make audio level adjustment, instead of use PWM to control DC volume level in TDA7056.
