26.2.1.1 Invalid Modes
The following mode combinations will trigger an interrupt to the interrupt controller and set the
mode error bit in the MDHA interrupt status register.

—
Asserting both of the signals at the same time causes a mode to
occur that the MDHA is not capable of performing. These two
modes must be performed separately.
According to HMAC and EHMAC standards no padding is done
to the data when the IPAD function is performed.
According to HMAC and EHMAC standards no padding is done
to the data when the OPAD function is performed.
MDHA requires that the IPAD step be performed as a separate
hash operation than message authentication.
MDHA requires that the OPAD step be performed as a separate
hash operation than message authentication.
The standard for EHMAC is only defined for the SHA-1
algorithm.
MDHA requires that the IPAD step be performed as a separate
hash operation than message authentication.
MDHA requires that the OPAD step be performed as a separate
hash operation than message authentication.
SSL MAC is only functional for the MD5 algorithm.
The SWAP bit is designed to support a particular function for the
SHA-1 algorithm and is invalid for MD5.
