Bit 7 – AES_ER AES_ER
This SRAM register bit indicates an error of the AES module. An error may occur for instance after an access to SRAM register 0x83 (AES_CTRL) while an AES operation is running or after reading less than 128-bits from SRAM register space 0x84 – 0x93 (AES_STATE).
| Value | Description |
|---|---|
| 0x0 | No error of the AES module |
| 0x1 | AES module error |
Bit 0 – AES_DONE AES_DONE
The bit AES_DONE signals the status of AES operation.
| Value | Description |
|---|---|
| 0x0 |
AES operation has not been completed |
| 0x1 | AES operation has been completed |
