x
= must be "0" for reading, can be "1" or "0" for writing to the TDA7529
d
= determinates the direction of data transfer, reading or writing
R / W = indicates the address to read to and/or to write from a single TDA7529
W
= indicates those addresses that can be used to transmit equal data to several TDA7529 frontends. A
read out has no purpose for these addresses (data collision), but must be possible without damaging
the tuner IC.
The two serial bus protocols, I²C and SPI, are as follows:
