Technical Note
? Writing protocol
A register address is transferred by the next 1 byte that transferred the slave address and the write-in command. The 3rd
byte writes data in the internal register written in by the 2nd byte, and after 4th byte or, the increment of register address is
carried out automatically. However, when a register address turns into the last address (1Ah), it is set to 00h by the next
transmission. After the transmission end, the increment of the address is carried out.
