3.6.3
The TDA5255 data output can be digital (pin 28) or in analog form by using the peak detector output
and changing some settings.
To get an analog data output the slicer must be set to lowpass mode (Reg. 0, D15 = LP = 0) and
the peak detector capacitor at pin 12 or 13 has to be changed to a resistor of about 47kOhm.
