For example: if the host’s sending address is 1, requests command of writing data
00 03 to register 2. Host send: 01 06 00 02 00 03 XX YY, thereinto, 01 as slave
address, 06 as function code, 00 02 as register address, 00 03 as written data and
XX YY as verification code.
Slave response: 01 06 00 02 00 03 XX YY, thereinto, 01 as slave address, 06 as
