Detailed Description

Args for CMAC generate and verify Note: These services are only available in HSSE mode.

Generate: on return ptrTag holds the full 16-byte AES-CMAC output. Verify: ptrTag must contain the expected 16-byte tag. ACK if tags match, NACK otherwise.

Parameters
ptrDataPointer to input data in shared memory
dataLenLength of input data in bytes
ptrTagPointer to 16-byte tag buffer (output for generate, expected tag for verify)
