● The field subindex is an 8-bit value that is transferred in the low-value byte (bits 0 to 7) of
the parameter index (IND).
● The task of selecting parameter pages for additional parameters is performed in this case
by the higher-value byte (bits 8 to 15) of the parameter index. This structure meets the
requirements of the USS specification.
Example: Coding a parameter number in PKE and IND for "p2029, Index 5"
