MC81212. OPERATION2.1 I 2 C2.1.1 OVERVIEWThe I 2 C is one of industrial standard serial communication protocols, and which uses 2 bus linesSerial Data Line (SDA) and Serial Clock Line (SCL) to exchange data. Because both SDA and SCLlines are open-drain output, each line needs pull-up resistor. The features are as shown below.- Compatible with I 2 C interface- Up to 400kHz data transfer speed- Support two 7-bit slave address- Slave operation only2.1.2 I 2 C BIT TRANSFERThe data on the SDA line must be stable during HIGH period of the clock, SCL. The HIGH or LOWstate of the data line can only change when the clock signal on the SCL line is LOW. The exceptionsare START(S), repeated START(Sr) and STOP(P) condition where data line changes when clock lineis high.SDASCLData line Stable:Data validexept S, Sr, PChange of DataallowedFigure 2-1 Bit Transfer on the I 2 C-Bus2.1.3 START / REPEATED START / STOPOne master can issue a START (S) condition to notice other devices connected to the SCL, SDAlines that it will use the bus. A STOP (P) condition is generated by the master to release the bus linesso that other devices can use it.A high to low transition on the SDA line while SCL is high defines a START (S) condition.A low to high transition on the SDA line while SCL is high defines a STOP (P) condition.May 2013 REV1.61 13
