Definition of each bit
1) Slave address
2) Register address
3) Register data
The slave address consists of seven-bit fixed address "1110000" or "1110001", which is unique to a chip, and the
eighth-bit data direction bit(R/W). Sending (writing) is processed when the data direction bit is"0", and receiving
(reading) is processed when it is "1". The fixed address is set to "1110001" at DEVAR=1 and it is set to "1110000" at
DEVAR=0.
Since the total number of internal register is 34, 2-bit data set on the MSB side becomes invalid. 64 addresses are
accepted 6 bits are used, but only 34 registers are used.
Each register data consists of eight bits.
