Function
Compare Modes:
0: Disables the module comparator function.
1: Enables the module comparator function. The comparator is used to implement the
software timer, high-speed output, pulse width modulation, and watchdog timer modes.
0: Disables the capture function with capture triggered by a positive edge on pin
CEX[4:0].
1: Enables the capture function with capture triggered by a positive edge on pin
CEX[4:0].
0: Disables the capture function with capture triggered by a negative edge on pin
CEX[4:0].
1: Enables the capture function with capture triggered by a negative edge on pin
CEX[4:0].
Match: Set ECOM[4:0] and MAT[4:0] to implement the software timer mode.
0: Disable the software timer mode
1: A match of the PCA timer/counter with the compare/capture register sets the
CCF[4:0] bit in the CCON register, flagging an interrupt.
Toggle: Set ECOM[4:0], MAT[4:0], and TOG[4:0] to implement the high-speed output
mode.
0: Disable the toggle function
1: A match of the PCA timer/counter with the compare/capture register toggles the
CEX[4:0] pin.
Pulse Width Modulation Mode:
0: Disable the pulse width modulation mode
1: Configures the module for operation as an 8-bit pulse width modulator with output
waveform on the CEX[4:0] pin.
Enable CCF[4:0] 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.
