Revision February, 2017 9-11
Example 2: function code 06H, write single word:
The Master issues command to the 1
st
Slave and writes data 0064H to address 0200H. The Slave
sends the response message to the Master after the writing is completed. The calculation of LRC
and CRC will be described in next chapter.
