8.5.1 I²C Byte Write
The transmission begins with a START condition (S), which consists of a high-to-low transition of the I2CD bus when I2CL is high. The START
condition is followed by the Device Write mode (DW), word address (WA: register address to write into) and the register data (reg_dat). Until the
stop condition (P) the word address is automatically incremented at any register data.
