For more details on the soft reset procedure, see Section 13.7.5.1.
To perform a software reset of the AES module, write 1 to the RESET bit in the SWRESET register. When the software reset completes, the RESET bit in the SWRESET register is automatically reset. Software must ensure that the software reset completes before starting any operations.
In the DMA control module, software reset is used to reset the DMAC to stop all transfers and clear the DMAPORTERR register. After the software reset is performed, all channels are disabled and no new requests are performed by the channels. The DMAC waits for the existing (active) requests to finish, then sets the DMAC status registers.
