sequence. Register AES_CTRL_MIRROR is a mirrored version of register 0x83
(AES_CTRL).
In summary, the following steps are required to perform a security operation using only
one SPI access:
1. Configure SPI access
2. Configure AES operation
3. Write 128-bit data block
4. Start AES operation
This sequence is recommended because the security operation is configured and
started within one SPI transaction.
The ECB encryption operation is illustrated in Figure 9-2. Figure 9-3 shows the ECB
decryption mode, which is supported in a similar way.

a) SRAM write, refer to section 4.3
b) Start address 0x83
Address 0x83: select ECB mode and direction
Addresses 0x84 – 0x93: either plain or cipher text
Address 0x94: start AES operation, ECB mode
