21.10 Amplifier Control Registers

The configuration of the amplifiers are controlled via two dedicated registers AMP0CSR and

AMP1CSR. Then the start of conversion is done via the ADC control and status registers.

The conversion result is stored on ADCH and ADCL register which contain respectively the most

significant bits and the less significant bits.
