27.4.2.1.1 Special Event Trigger
In select devices, the Dual 16-Bit Timer mode can be used to generate a Special Event Trigger output signal. The primary timer can be used to start A/D conversions and trigger other peripheral events. The trigger period is set by the value of the CCPxRB register and must be less than the counter period, as defined by the CCPxPRL register bit locations.
