TPG110 inputs the setting values via SDA on the rising edge of input SCL.
command. “0” is write command. “1” is read command. Then, the next cycle is turn-round cycle.
Finally, the last 8 bits are for Data setting (D7 ~ D0). The address and data are transferred from the
MSB to LSB sequentially. The data is written to the register of assigned address when “End of
transfer” is detected after the 16th SCL rising cycles. Data is not accepted if there are less or more
than 16 cycles for one transaction.
The first 6 bits (A5 ~ A0) specify the address of the register. The next bit means Read/Write
