STMicroelectronics /STM32U083 /AES /AES_DINR

Data input A four-fold sequential write to this bitfield during the Input phase results in writing a complete 16-bytes block of input data to the AES peripheral. From the first to the fourth write, the corresponding data weights are [127:96], [95:64], [63:32], and [31:0]. Upon each write, the data from the 32-bit input buffer are handled by the data swap block according to the DATATYPE[1:0] bitfield, then written into the AES core 16-bytes input buffer. Reads return zero.
