REMARKS
Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
For the instruction codes HFF, HEC and HF3, their values are held once written but cleared to zero when an inverter reset or all
clear is performed.
Example) When reading the C3 (Pr. 902) and C6 (Pr. 904) settings from the inverter of station No. 0
