You did not say what version you are reading (why not?), but...

I just now downloaded the current datasheet for PIC12F683 from
Microchip, 41211D_.PDF (don't ask me what the underscore does there)
The datasheet is dated 2007, b.t.w.

On page 77, section "11.2 Compare Mode" it says:

"When a match occurs, the CCP1 module may:
- Toggle the CCP1 output.
- Set the CCP1 output.
- Clear the CCP1 output.
- Generate a Special Event Trigger.
- Generate a Software Interrupt."

I have an older version ("B", from 2004) it it says :

"When a match occurs, the GP2/AN2/T0CKI/INT/COUT/CCP1 pin is:
- Driven high
- Driven low
- Remains unchanged"


Weird...

Jan-Erik.
