The pointer interpreter will transition into the NDF state based on the following conditions:
— If NDF is enabled on the incoming V1 and V2 bytes, the pointer interpreter will transition from the NORM, NDF,
The pointer interpreter will transition out of the NDF state based on the following conditions:
— Continuous NDF. If NDF (1001, 0001, 1101, 1011, 1000) is received for the number of consecutive super-
