5.3.2 CheckMac Command
The CheckMac command calculates a MAC response that would
have been generated on a different CryptoAuthentication™ (ATECC608B, ATECC508A, ATSHA204A) device and then compares the result with the
input value. The command returns a boolean result to indicate the success or failure of
the comparison.
If a value in TempKey is used as an input to the CheckMac,
then a Nonce and/or GenDig command must be run prior
to the CheckMac command.
