Chapter 13: SHA-1
13.1 Programming Guide
13.2 SHA-1 Registers (Base → FFFF9000h)
13.2.1 Offset 000h: SHA1_H – Hashed Value
13.2.2 Offset 014h: SHA1_DATA_IN – Data In
DS0200-003
The SHA-1 module provides a message digest for given text of almost any length per the SHA-1 protocol.
To generate a hashed signature value, execute the following actions:

127:96

Bits
If the existing hash value is acceptable, set SHA1_CONTROL.INIT to ‘1’. Alternatively, write
SHA1_WH
SHA1_CONTROL.INIT_SEL to ‘1’.
Write a value to SHA1_DATA_IN.DATA. Sixteen writes to W_IN must be performed to provide
data to the SHA-1. DMA can be used to provide these values.
Wait for 65 clocks and read SHA1_STATUS.VALID. Once this bit is set, SHA1_H contains the
output. SHA1_STATUS.VALID remains set until all 5 registers are read.
