Reserved

The Value read from this bit is indeterminate. Do not set this bit.

Enable Compare Mode Module x bit

Clear to disable the Compare function.

6

ECOMn Set to enable the Compare function.

The Compare function is used to implement the software Timer, the high-speed

output, the Pulse Width Modulator (PWM) and the WatchDog Timer (WDT).

Capture Mode (Positive) Module x bit

5

CAPPn Clear to disable the Capture function triggered by a positive edge on CEXx pin.

Set to enable the Capture function triggered by a positive edge on CEXx pin

Capture Mode (Negative) Module x bit

4

CAPNn Clear to disable the Capture function triggered by a negative edge on CEXx pin.

Set to enable the Capture function triggered by a negative edge on CEXx pin.

Match Module x bit

3

MATn Set when a match of the PCA Counter with the Compare/Capture register sets

CCFx bit in CCON register, flagging an interrupt.

Toggle Module x bit

2

TOGn

The toggle mode is configured by setting ECOMx, MATx and TOGx bits.

Set when a match of the PCA Counter with the Compare/Capture register

toggles the CEXx pin.

Pulse Width Modulation Module x Mode bit

1

PWMn Set to configure the module x as an 8-bit Pulse Width Modulator with output

waveform on CEXx pin.

Enable CCFx Interrupt bit

0

ECCFn Clear to disable CCFx bit in CCON register to generate an interrupt request.

Set to enable CCFx bit in CCON register to generate an interrupt request.

Reset Value = X000 0000b
