31.6.4 Sleep Mode Operation

The TRAM continues to operate during sleep. When it receives events from the Event System, it will request its own clock in order to perform the requested operation.

An interrupt request will be generated after the wake-up if the Interrupt Controller is configured accordingly. Otherwise the CPU will wake up directly, without triggering an interrupt. In this case, the CPU will continue executing from the instruction following the entry into sleep.

The periodic events can also wake up the CPU through the interrupt function of the Event System. In this case, the event must be enabled and connected to an event channel with its interrupt enabled. See EVSYS – Event System for more information.
