The Register Interface block performs all address decoding and control; however, not all registers are located in this block. The context and data input registers are located in the AES Wide-bus Engine.
The Data Output Registers are available in this block. Each HIB has one dedicated data output register, along with a single 128-bit overflow register shared by both HIBs. The overflow register is used in case one HIB stalls such that its data output is not read in time. To prevent the other HIB from being blocked as a consequence, the result data is ‘parked’ in the overflow register.
