The Mode Control FSM manages the data flow to and from the AES Wide-bus Engine. The block generates the rfd_in and xxx_out_av signals and monitors the rfd_out/rft_out signal. Refer to Figure 2. It also sends a start pulse to the encrypt/decrypt cores when both rfd_in and d_in_av are asserted, and triggers the core to use the new mode and keys when both rfc_in and c_in_av are asserted.
