As soon as a conversion is requested thanks to the ADSC bit, the Analog to Digital Conversion
is started. In case the amplifier output is modified during the sample phase of the ADC, the
on-going conversion is aborted and restarted as soon as the output of the amplifier is stable.
This ensure a fast response time. The only precaution to take is to be sure that the trig signal
(PSC) frequency is lower than ADCclk/4.
