ReturnCode
The response packet for each ATAES132 command includes a ReturnCode to report success or failure to the host. The first
four error codes (0x01 through 0x08) may occur concurrently with other codes.
The reset command and the sleep command do not generate a ReturnCode because they do not generate a response packet.
All other ATAES132 commands generate a ReturnCode.
Table 6-16. ReturnCode field sorted by Value
If ReturnCode has any value other than 0x00, no additional data will be returned by ATAES132. If the ReturnCode is greater
than zero for any command that performs cryptographic operations, then the nonce will be invalidated.
