CheckMac,
GenDig, HMAC, Lock,
Nonce, Pause, Random,
SHA, and UpdateExtra commands have been
removed.
The DeriveKey command
uses the key in Slot 15 (ParentKey slot) and various constants to derive a key and store
it in Slot 7 (DerivedKey slot). Param1 and Param2 have no effect on the operation of the
command. There is no flexibility in source and target locations.
The MAC command
computes a digest of Slot 7 and outputs the digest. Param1 and Param2 values have no
effect on operation.
The Nonce command is a
null operation and does not generate an output.
The Read command
operates the same as the SHA204A but the slots in which it can be read are limited. All
the configuration zones can be read.
The Write command is
limited to writing Slots 8-10 (DataStore Slots 0, 1 and 2), once the part has been
locked and/or shipped.
