27.4.5 Module Sync Outputs
By default, the CCP module generates a CCP Sync signal from the rollover of the CCPxTMR register. This signal is made available to all of the other CCP modules as a Sync source, or it is made available to trigger another peripheral. The CCP Sync signal is separate from the module’s device-level interrupts or other outputs.
There may be circumstances where another event signal may serve as a better basis for the CCP Sync signal or where an additional event output, other than the selected signal, is required. The CCP modules include user configuration options to handle these situations.
