The mode control FSM manages the data flow to and from the DES engine. This block also sends a start pulse to the encrypt or decrypt core and triggers the core to use the new mode keys when a new context is needed. This module also controls the 3DES operation, such that the DES core module is triggered three times (with different keys) before the result data becomes available.
