I²C CONTROL INTERFACE
Data are transmitted to and from the MCU and MS6336 via the SDA and SCL. The SDA and SCL make up the
BUS interface. It should be noted that pull-up resistors must be connected to the positive supply voltage.

I²C interface protocol
The format consists of the following:
•A START condition
•A chip address byte including the chip address. (7bits)
•The 8^th bit of the byte must be “0”.(write=0, read=1)
•The chip must always acknowledge the end of each transmitted byte.
•A data sequence (N-bytes + Acknowledge)
•A STOP condition
