On Page 53 of UM10503.pdf, the dummy tag value for the CMAC hash calculation is given as 0x3456789A.

The problem is, that's a 32bit value and the HASH_VALUE field is 64 bits wide.   Should we repeat the value across the 64bits, or pad with something at top or bottom, or is the value just given incorrectly in the datasheet?
