Bits 31:0 – DATA[31:0] Data Value
A write to or read from this register corresponds to a write to or read from one of the four data registers.
The four 32-bit Data registers set the 128-bit data block used for encryption/decryption. The data register
that is written to or read from is given by the DATABUFPTR.DATPTR field.
Note: Both input and output shares the same data buffer. Reading DATA register will return 0’s when
AES is performing encryption or decryption operation.
