Function
7:0 AES0YOUT[7:0] AES Y Output.
Upon completion of an encryption/decryption operation The output data may be
read, one byte at a time, from the AES0YOUT SFR.
When used with the DMA, the DMA will read directly from this SFR.
The AES0YOUT SFR may be used in conjunction with the AES0XIN SFR for
some cipher block modes.
When used without the DMA, the firmware should wait on the DONE flag before
reading from the AES0YOUT SFR.
When used without the DMA and using XOR on the output, one byte should be
written to AES0XIN before reading each byte from AES0YOUT.
Reading this register over the C2 interface will not increment the output data.
