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. All registers are

initialized, regardless of mode selected, however only the appropriate context register values are used in

hash generation per the mode selected. The user typically does not care about the MDEU context register

initialization values, however they are documented for completeness in the event the user reads these

registers using host-controlled access. MDEU reset through the MDEU reset control register

14.4.2.12 MDEU Key Registers

The MDEU maintains eight 64-bit registers for writing an HMAC key. The IPAD and OPAD operations

are performed automatically on the key data when required.
