DQPSK Configuration

Using the CCSDS DNRZ code and its decoding look-up table:
In 1 1 0 0 0 1 0 1 1 0 1 0 0 0 1 1
Qn 1 0 1 0 1 1 0 0 0 0 1 1 0 1 0 1
To select this code in the registry, set the Cortex HDR ICD parameter to 1 (code number in the left-
hand column of the above table) or enter the DNRZ code value (0xC5A3AC35) as defined in the above
decoding table).
Selection of the other codes follows the same rule.
