Two wires ( SDA - serial data, SCL - serial clock ) realize functions of start , stop , transferring data , synchronization and arbitration. The output stages of device connected to the bus must have an open drain or open collector in order to perform the wired-AND function . SDA A A LSB MSB MSB LSB SCL S P 1 2 3 5 4 6 7 9 8 1 2 9 S ; Start condition, a high to low transition of the SDA line while SCL is high P ; Stop condition, a low to high transition of the SDA line while SCL is high A ; Acknownledge Every byte put on the SDA line must be 8-bits long . Each byte has to be followed by an acknowledge bit. Data is transferred with the most significant bit (MSB ) first . The data on the SDA line must be stable during the HIGH period of the clock . The HIGH or LOW state of the data line can only change when the clock signal on the SCL line is LOW . CONTROL This IC controls 2-channel switchs with 2-byte data ( DATA1 and DATA2 ) . Video switches are controled by DATA1 , audio switches are controled by DATA2 .
