SMOD
The processing time represents the number of clock cycles that the AES needs in order to perform one encryption/decryption
with no countermeasures activated:
The best performance is achieved with PROCDLY equal to 0.
Writing a value to this field will update the processing time.
Reading this field will give the current processing delay.
0: Decrypts data is enabled.
1: Encrypts data is enabled.
