Prescaler control: PSC = 0 for prescaler not active. Internal
master clock of ADC is equal to the internal chip clock.
PSC = 1 for prescaler active. Internal master clock of ADC is
at half the internal chip clock.
ADC sample time adjustment: STADC = 0 for normal sample
time. STADC = 1 for fourfold sample time.
ADC interrupt request flag. Set on completion of AD-
conversion. Must be cleared by software.
Busy flag; = 1, during conversion.
ADC-conversion mode: ADM = 0 for single and ADM = 1 for
continuous conversion.
Always to be written with ‘0’.
