CAPPn
The Value read from this bit is indeterminate. Do not set this bit.
Clear to disable the Compare function.
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).
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
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.
Set when a match of the PCA Counter with the Compare/Capture register sets CCFx bit in CCON
register, flagging an interrupt.
Must be cleared by software.
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.
Must be cleared by software.
Set to configure the module x as an 8-bit Pulse Width Modulator with output waveform on CEXx pin.
Must be cleared by software.
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.
