12.4.4.11 MDEU Context Registers
For the MDEU, the context consists of the hash plus the message length count. Write access to this register
block allows continuation of a previous hash. Reading these registers provide the resulting message digest
or HMAC, along with an aggregate bit count.
After a power-on reset, all the MDEU context register values are cleared to 0.
MDEU context registers are initialized if the INIT bit is set in the MDEU mode register.

SHA-1and SHA-256 are big endian. MD5 is little endian. The MDEU
module internally reverses the endianness of the five registers A, B, C, D,
and E upon writing to or reading from the MDEU context if the MDEU
mode register indicates MD5 is the hash of choice. Most other endian
considerations are performed as 8-byte swaps. In this case, 4-byte
endianness swapping is performed within the A, B, C, D, and E fields as
individual registers. Reading this memory location while the module is not
done will generate an error interrupt.
