DMA Done Flag Mask for DMA Operation
This field sets the behavior of the CRYPTO_CTRL.done flag. Setting this bit
to 1 results in a CRYPTO_CTRL.dma_done complete to set the
CRYPTO_CTRL.done field. The setting for this field does not affect the
actual behavior of the CRYPTO_CTRL.dma_done flag.
0: DMA Complete Flag is not used for setting CRYPTO_CTRL.done field.
1: DMA Complete condition sets the CRYPTO_CTRL.done field.
