it will process the result in about 8000 cycles on the current platform. Please note that the function:
1) Always uses 128 bit (16 bytes) inputs/output.
2) Is not re-entrant (and is not re-entrant with execution of the CCMStar function either).
3) It is allowed to set the ReturnData pointer to the same memory as either Data or Key if wanted.

/************************************************************************************
* Perform AES-128 cryptographic operation on a data set. Optimized for 8 bit
* processors. The result will be processed in about 8000 cycles on the HCS08 platform
* Please note that for HCS08 projects the architecture definitions must locate the
* internal buffers (MY_ZEROPAGE) in lower memory space for correct linking.
*
* Interface assumptions:
*   All input/outputs are 16 bytes (128 bit).
*   Please note that the function is not re-entrant. Also, it is of course not re-
*   entrant with other functions calling this function (like SecLib_CcmStar).
*   It is allowed to point the ReturnData pointer to the same memory as either Data or
*   Key if wanted.

* Return value:
*   None
