Example 3: function code 10H, write multiple words:
The Master issues command to the 1
address 0112H. That is to say, 0112H is written into 0BB8H and 0113H is written into
0000H. The maximum allowable data in one single access is 10. 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.
