The master control module synchronizes the DMA operations and the cryptographic module handshake signals. In this module, the crypto algorithm is selected and the DMA burst sizes are defined. When the complete encryption operation completes, an interrupt is asserted.
For authentication operations, the interrupt is asserted only if the authentication result is available.
The AES module also provides an interrupt to indicate that the input DMA transfer is complete. This interrupt is primarily used to determine the end of an AAD data DMA transfer (AES-CCM), which is typically set up as separate input data transfer.
