Port Number: 2000-2???

Memory-mapped Address: E10000-E1????

Function: Cryptography

This is the SHA256 chip. It is very similar to [1]. The block and state are split into 32-bit little-endian words (inputs and hashes are generally displayed big-endian), but TI fails to compensate for this. This port is protected. Protected ports must be unlocked to read and write to these ports. Additionally, flash must be unlocked for the chip to function.
