C protocol communication is a two-wire serial transmission. It is a half-duplex protocol where data can be transferred at various baud rates: up to 100Kbits
(100Kbps) in standard mode and up to 400Kbits (400Kbps) in fast mode.
Transfer Protocol
Each transfer is made of a start bit followed by one or more sequences of eight data bits, acknowledge bit(s) sent by the receiver, and a stop bit. Data is sent with
the most significant bit (MSB) first. Every byte delivered to the SDA line must be eight bits long; however, the number of bytes that can be transmitted per transfer is
unrestricted.
