Ongoing AES operation cannot be aborted by writing to AESAXIN
Writing to AESAXIN register when AESASTAT.AESBUSY bit is set does abort the ongoing AES operation or set the AESACTL0.AESERRFG bit.
Always let AES operation run to completion (i.e. do not abort). Ignore the encryption/decryption output if AESAXIN is written when AESASTAT.AESBUSY is set.
