If the CFlist is not empty then the CFListType field SHALL contain the 502 value one (0x01) to indicate the CFList contains a series of ChMask fields. The ChMask 503 fields are interpreted as being controlled by a virtual ChMaskCntl that initializes to a value of 504 zero (0) and increments for each ChMask field to a value of four (4).
