Communication using the SPI protocol
For SPI communication, pin "PS" needs to be connected to GND.
No IC address is transmitted in SPI mode, as in this mode the chip is selected through its
CS (Chip Select) line.
SPI-Protocol: CPOL=1, CPHA=1

= must be "0" for reading, can be "1" or "0" for writing to the TDA7528
= determinates the direction of data transfer, reading or writing
= indicates those addresses that can be used to transmit equal data to several TDA7528s, e.g. to
program an synchronous AF jump of two tuners. A read out has no purpose for these addresses.
