C Compatible Bus
The first and third data bytes contain a function bit which lets the IC distinguish between frequency
information and control information. If the function bit is a logic 1, the two following bytes contain control
information. The first data byte after the chip address may be byte CO or byte FM. The two bytes of
frequency information are preceded by a logic 0.
13.6 I

C Read Mode Format
The chip address (I

C) is:
The incoming information consists of the read mode chip address byte. The device then answers with an
ACK followed by one byte containing three bits of status information. No acknowledge is answered by the
modulator after this byte.
