In the Application Note (AN12196), it defines the calculation of MACt in section 3 as below:
In section 4.4.4.2, where CMACInputOffset == CMACOffset, in the SDMMAC calculation, it shows the example,
You will notice that the SDMMAC (94EED9EE65377086) doesn't contain the even bytes of the session key K (3FB5F6E3A807A03D5E3570ACE393776F).
However, the defined pattern holds for section 4.4.4.2.2, where CMACInputOffset != CMACOffset,
And for 5.3 CommMode.MAC,
And for 5.4 CommMode.Full,
And for 6.8.2 Write NDEF File - using Cmd.WriteData, CommMode.FULL
And others.
Why is it the case that the Truncated MAC calculation for the example in 4.4.4.2 is different than the others?
Thanks!
