C bus Protocols
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”.
STA: Start Condition
STO: Stop Condition
CA: Chip Address
CB: Control Byte
BB: Band switch Byte
D1: Divider Byte 1
D2: Divider Byte 2
