Bits 31:0 – IDATA[31:0] Input Data Word

The four 32-bit Input Data registers set the 128-bit data block used for encryption/decryption.

AES_IDATAR0 corresponds to the first word of the data to be encrypted/decrypted, and AES_IDATAR3 to the last one.

These registers are write-only to prevent the input data from being read by another application.
