The purpose of the initialization is to set the AES module into the initial mode common to all used operations. Perform the following initialization steps after a hardware reset:
- Read out and check that the AES module version and configuration matches the expected hardware configuration.
- Program the DMAC run time parameters in the DMABUSCFG register with the desired values common for all DMA operations.
- Initialize the desired interrupt type (level), and enable the interrupt output signal RESULT_AVAIL in the master control module.
