How to disable C2OUT when using half bridge mode pic 16f684
PostPosted: Thu Jan 18, 2018 10:32 pm     Reply with quote
Hi everyone,

I saw the recommend on 16f684 datasheet and it said:
" 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 vice-versa".

Can anyone help me how to enable and disable C2OUT when using HALF BRIDGE MODE.

Thank you and best regards!

C2OUT is controlled by a bit in the CMCON0 register. That bit is disabled
upon power-on reset of the 16F684. It is normally disabled. You don't
have to worry about adding code to disable it.

If you did want to put in code to disable it, you could do it this way:
Code:
C2OUT = 0;

The 16F684.h file has the #byte statement for C2OUT in it. So that line
of code will compile OK.

But again, it should not be needed.
