5.3.4. Data AES Decryption

The configuration data interface can also be used to transmit data from the HPS to the FPGA CSS Advanced Encryption Standard (AES) decryption engine. Software should sample the status registers in FPGA manager before switching modes between FPGA configuration and AES decryption. The FPGA manager does not do anything specific to handle a situation where software starts an AES decryption while in the middle of an FPGA configuration initiated by HPS, and the end result in this case is undefined.
