This reg contains the total size of the data written to REG_SHA_IN. | This reg contains the total size of the data written to REG_SHA_IN, this field is updated when performing hash-function final-round. | ||

This reg contains the SHA* hash after the final round, and the internal state during normal rounds. It is possible to write the internal state using this register. | This reg contains the SHA* hash after the final round, and the internal state during normal rounds.
