TDA 6160-2X
eighth bit is always low. The first bit of the first or third data byte in the data part of the telegram
determines whether a divider ratio or control information will follow. In every case the first byte must
be followed by a byte of the same data type (or a stop condition). When the supply voltage is
applied, a power-on reset circuit prevents the PLL from pulling the SDA-line to low and thus blocking
the bus.
