GPIO - general purpose I/O interface pins
The TDA7528 has eight GPIO - general purpose - control pins (GP1...GP8) to switch
external stages (output), e.g amplifiers, or to read the status of external stages (input), e.g.
control voltages. Some control pins are multiplexed with other functions that are not
necessary in every tuner design.
3.11.1
Serial data interface
The TDA7528 features a serial data port for communication with the microcontroller. It is
used to program the TDA7528 and to convey the read-out values of its detectors. This port
supports data communication using the SPI and the I2C protocols.
