7.3.2.4 Command code 10H, continuous writing
Command code 10H means that the master writes data to the VFD while the number of data
pieces depends on the "data count" in the command code. A maximum of 16 pieces of data
can be continuously written.
For example, to write 5000 (1388H) to 0004H and 50 (0032H) to 0005H of the VFD whose
slave address is 02H, the frame structure is as follows:
