The mode register is cleared when the MDEU is reset or re-initialized. Setting a reserved mode bit
generates a data error. If the mode register is modified during processing, a context error is generated.

Reserved
Selects which algorithms are enabled by the ALG bits.
0 MDEU-A enables selection between SHA-1, SHA-256, MD5, and SHA-224
1 MDEU-B enables selection between SHA-384, SHA-256, SHA-512, and SHA-224.

Determines the configuration of the MDEU Mode Register. This table shows the
configuration for NEW=0.
Reserved, must be cleared.
Continue: Most operations require this bit to be cleared. It is set only when the data to be
hashed is spread across multiple descriptors.
The value programmed in PD must be opposite to the value in this bit.

Compare Integrity Check Values:
0 Normal operation; no ICV checking.
