Data transfer writing format

In the first one byte, the slave address and the Write command are allocated, and the following one byte specifies the

register address in the cereal map.

The register address is done after the fourth byte be to do the data transfer to the address specified in the register address

written in the third byte and the 2nd byte, and to continue data after that and the increment is done by the automatic

operation.

As a result, a data continuous sending from a specified address becomes possible.

However, when the address becomes 3fh, the forwarding address of the following byte becomes 00h.
