The following list describes the requirements for
initializing the SHA/MD5 and associated modules:
- Configure the SHA DMA channels for
Context In, Context Out, Data In, or Data Out by programming the appropriate encoding
value.
- If the SHA channels are configured in the DMA,
enable the required SHA DMA requests by programming bits [9:5] of the
S_SYSCONFIG register, in addition to the completion interrupts in the SHA
DMA Interrupt Mask (S_SHA_IMST) register, CRC, and cryptographic modules
offset 0x020.
