Integrity check error
0 No error detected
1 Integrity check error detected. An ICV check was performed and the supplied ICV did not match the one
Reserved
Internal error. An internal processing error was detected while the AESU was processing.
0 No error detected
1 Internal error
Note: This bit will be asserted any time an enabled error condition occurs and can only be cleared by setting the
Early read error. The AESU IV register was read while the AESU was processing.
0 No error detected
1 Early read error
Context error. An AESU key register, the key size register, data size register, mode register, or IV register was
modified while AESU was processing
0 No error detected
1 Context error
Key size error. An inappropriate value (not 16, 24 or 32bytes) was written to the AESU key size register
0 No error detected
1 Key size error
Data size error (DSE): A value was written to the AESU data size register that is not a proper size. See
Section 12.4.6.3, “AESU Data Size Register (AESUDSR).”
0 No error detected
1 Data size error
Mode error. Indicates that invalid data was written to a register or a reserved mode bit was set.
0 Valid data
1 Reserved or invalid mode selected
Address error. An illegal read or write address was detected within the AESU address space.
0 No error detected
1 Address error
