SAA7706H audio input selection

Question asked by Martin Svaton on Oct 3, 2018

Good afternoon,


I have question regarding to the DSP controller SAA7706H, which is processing audio signal and is installed in variety of car stereos. I need to set the TAPE analog input as active and I did not find any reference regarding to the i2c memory map and what exact bytes must be set via I2c to activate the input. Is there any other reference, which is describing particular bits in each register? 


Thank you.
