When DMA support is enabled by setting SCR[DMAEN] and the interrupt is enabled by
setting SCR[IER], SCR[IEF], or both, the corresponding change on COUT forces a DMA
transfer request to wake up the system from STOP modes. After the data transfer has
finished, system will go back to STOP modes. Refer to DMA chapters in the device
reference manual for the asynchronous DMA function for details.

The comparator can remain functional in STOP modes.
