0x08 VCO sensor register

Only the temperature sensor or the peak detector can be enabled at a time. The temperature sensor is using a reference (diode row = 0)

and a signal branch (diode row = 1) only the absolute difference between these two voltages gives a voltage with is proportional to

temperature, and peak voltage level. Example for the temperature sensor activation is as follows.
