Offset and page index of the parameter numbers
Parameter numbers < 2000
PNU = parameter number.
Write the parameter number into the PNU (PKE bit 10 ... 0).
Parameter numbers
≥ 2000
PNU = parameter number
- offset.
Write the parameter number minus the offset into the PNU
(PKE bit
10 … 0).
Write the offset in the page index (IND bit 7 … 0).
