calculation input, the analog reference voltage
(Vref+) must be defined as it impacts the ADC
LSB equivalent voltage. Analog reference
voltage (Vref+) must be known from user board
environment or can be calculated using ADC
measurement. ADC measurement data must
correspond to a resolution of 12bits (full scale
digital value 4095). If not the case, the data
must be preliminarily rescaled to an equivalent
resolution of 12 bits.
Description:
Write a value in ADC register.

Return value:
None
Description:
Read a value in ADC register.
Parameters:
