The 512-bit message block that will be hashed with the SHA-256 algorithm will consist of:
If the overwrite parameter is 0, then the 512-bit message block that will be hashed using the SHA-256 algorithm
will consist of:
If the overwrite parameter has a value of 0x01, then the 512-bit message block that will be hashed using the SHA-
256 algorithm will consist of:
All other values of the overwrite parameter are not recommended for use.
HOST1
Completes the two block SHA-256 digest started by HOST0 and leaves the resulting digest within the internal
memory of the Atmel
previously within this Wake cycle.
As a security precaution, this command does not return the digest. A subsequent command is required to
compare the response generated by the client with the one generated by the host.
