During an encryption operation, the plaintext is written to the AES0BIN sfr. During
an decryption operation, the ciphertext is written to the AES0BIN sfr. During a key
inversion the encryption key is written to AES0BIN.
When used with the DMA, the DMA will write directly to this sfr.
The AES0BIN may be used in conjunction with the AES0XIN sfr for some cipher
block modes.
When used without the DMA, AES0BIN, AES0XIN, and AES0KIN must be written
in sequence.
Reading this register will yield the last value written. This can be used for debug
purposes.
