Write or can write ‘1’ to clear (WOC).
0 - Total Length is not expired or HMAC is not done with the packet.
1 - Total Length has expired and HMAC is done with the packet.
Bit 1
Hash Done - Indicates Hash Digest is valid. This bit is reset with a Context Write
or can write ‘1’ to clear (WOC).
0 - Hash Digest is not valid.
1 - Hash Digest is valid.
Bit 0
DES Done - Indicates the DES processing has completed. This bit is reset with a
