I2C bus specification
5.1
Interface protocol
The interface protocol comprises:
● a start condition (S)
● a chip address byte (the LSB determines read/write transmission)
● a subaddress byte
● a sequence of data (N-bytes + acknowledge)
● a stop condition (P)
● the max. clock speed is 400 kbits/s
● 3.3 V logic compatible
