I2C bus Protocols
The input information, which consists of chip address and next two or four byte data, is received by I2C 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”.
