27.5.2 Power Management

The DMAC channels with CHCTRLA.RUNSTDBY = 1 continue to operate in Idle mode. In Standby Sleep mode, the DMAC becomes internally disabled but maintains its current configuration. The DMAC can support Sleep-walking/Dream mode. The DMAC’s interrupts can wake up the device from sleep modes. Events connected to the event system can trigger other operations in the system without exiting sleep modes. On a hardware or software reset, all registers are set to their reset values.
