IND structure acyclic
in the low-order byte (bits 0 to 7) of the parameter index (IND).
the high-order byte (bits 8 to 15) of the parameter index. This structure conforms to the
USS specification.
Example: Coding for parameter no. in PKE and IND for "P2016, Index 3".
IND structure cyclic
in the high-order byte (bits 8 to 15) of the parameter index (IND).
