This command writes data to random (non-continuous) addresses in two-byte
units. Data is expressed as four hexadecimal digits.
● Send message
Data is sent for the specified write data count with the data address (four
hexadecimal digits) of the data to be written and the data (four hexadecimal digits)
as a pair.
● Response message
If writing is successful, the normal termination code (two decimal digits) is
returned. If only part of the data is written, and the remaining data is not written,
the warning termination code (two decimal digits) is returned. If none of the data
is written, the abnormal termination code (two decimal digits) is returned.
