40.6.7 Sleep Mode Operation

The TC can be configured to operate in Idle and Standby Sleep mode. To be able to run in Standby Sleep mode, the RUNSTDBY bit in the Control A register (CTRLA.RUNSTDBY) must be ‘1’. This peripheral can wake up the device from Idle and Standby Sleep mode using interrupts or perform actions through the Event System.

If the On Demand bit in the Control A register (CTRLA.ONDEMAND) is written to '1', the module stops requesting its peripheral clock when the STOP bit in the STATUS register (STATUS.STOP) is set to '1'. When a re-trigger or start condition is detected, the TC requests the clock before the operation starts.
