30.5.1 CCPxCON
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.
