3: Priority Setting (4 bits) – set this field's value to 0x8, which indicates to leave priority
settings unchanged.
4: Reserved (4 bits) – set this field's value to 0xF, which is the value for a reserved field
of this size.
5: Number of Pairs of Commanded Parameters to Follow (8 bits) – set this field's value
to the number of configurations to be changed.
6: Field number of first commanded parameter (8 bits). Please refer to the table below
for valid values for this field.
7: Value of first command parameter (size depends on the field number specified in
field 6 of this PGN) – please refer to the description of PGN 129538 above for
details.
Fields 6 and 7 are repeated pair wise until all parameters to be modified have been specified.
