The accessible data (holding register) address range is from 0000H to 02EEH and 1388H to
14A0H. Addresses in which data (holding register) is accessible are from 0000H to 02EEH
and from 1388H to 14A0H. If any address other than 0000H to 02EEH and 1388H to
14A0H is accessed, an error response message (error code: 2) returns.
However, no error returns for any address from 03E8H to 0563H. Therefore, do not access
any of the above addresses.
