enabled NDF + dd + “1111111111”
H1 = FFh + H2 = FFh
not any of the above (i.e.: not CONC_IND and not AIS_IND)
enabled NDF is defined as the following bit patterns:
1001, 0001, 1101, 1011 and 1000.
the remaining eleven NDF bit patterns (0000, 0010, 0011,
0100, 0101, 0110, 0111, 1010, 1100, 1110, 1111) result in an
