- When the BCC calculation result is 0002h, the converted data will be 3032h.
- When the converted data is 3032h, the data for comparison with the BCC part of the receive data will be
3032h.
- The comparison data is compared with the BCC part of the receive data.
In the following receive data, when the comparison data is the 2-byte 3032h, there is a match since the BCC part
data is 3032h.
When there is no match, the BCC Error (address number+0, bit 0) of Status Device Address changes to 1.
• When data reception is successfully completed, the Completed Device Address LM203 changes to 1.
