The RTC module includes a function called PIT. The PIT uses the same clock source as the rest of the RTC, and when enabled, provides a set of output events in the form of clock signals with periods corresponding to n times the RTC clock period. The different PIT output events are selectable in the Event System in the form of a set of predefined event generators, each with a different period relative to the RTC clock.
In order to use the PIT, output events the PIT must be enabled in the RTC module.
