n I2C bus Protocols 2 The input information, which consists of chip address and next two or four byte data, is received by I C bus receiver. The allowable I2C bus protocols are as follows. (1) STA CA CB BB STO (2) STA CA D1 D2 STO (3) STA CA CB BB D1 D2 STO (4) STA CA D1 D2 CB BB STO STA: Start Condition STO: Stop Condition CA: Chip Address CB: Control Byte BB: Band switch Byte D1: Divider Byte 1 D2: Divider Byte 2 For suitable circuit operation,5-byte data should have chip address, 2-byte control data, band data, and 2-byte divider byte. Following chip address. 2-byte data is received. For distinction of each data, first and third data byte has a function bit. As function bit, divider byte has "1" and control/band data has "0".
