Function
Not implemented, reserved for future use.
Note: User should not write ‘1’s to reserved bits. The value read from a reserved bit is indeterminate.
Enable Comparator
0: Disables the comparator function
1: Enables the comparator function
Capture Positive
0: Disables positive edge capture on CEX[4:0]
1: Enables positive edge capture on CEX[4:0]
Capture Negative
0: Disables negative edge capture on CEX[4:0]
1: Enables negative edge capture on CEX[4:0]
Match: Set ECOM[4:0] and MAT[4:0] to implement the software timer mode
0: Disables software timer mode
1: A match of the PCA counter with this module’s compare/capture register causes the
CCFn bit in CCON to be set, flagging an interrupt.
Toggle
0: Disables toggle function
1: A match of the PCA counter with this module’s compare/capture register causes the
the CEXn pin to toggle.
Pulse Width Modulation mode
0: Disables PWM mode
1: Enables CEXn pin to be used as a pulse width modulated output
Enable CCF Interrupt
0: Disables compare/capture flag CCF[4:0] in the CCON register to generate an
interrupt request.
1: Enables compare/capture flag CCF[4:0] in the CCON register to generate an
interrupt request.
