28.5.1 CCPxCON

CCP Control Register

Note:

The set and clear operations of the Compare mode are reset by setting MODE = ‘b0000 or EN = 0.
When MODE = ‘b0001 or ‘b1011, then the timer associated with the CCP module is cleared. TMR1 is the default selection for the CCP module, so it is used for indication purposes only.
