A/D Converter (ADC)

Diagnostic mode
When activating the diagnostic mode (ADADIAG bit of ADAnM2 register is set)
the voltage at the AVREF pin and the AVSS pin are sampled after conversion
of the specified ANInm range is finished.
The resulting values can be found in the ADAnCRDD, ADAnCRDDH,
ADAnCRSS and ADAnCRSSH registers.
Since AD conversion accuracy is influenced of use conditions, the result does
not necessarily become all 1 when converting AVREF.
Since AD conversion accuracy is influenced of use conditions, the result does
not necessarily become all 0 when converting AVSS.
Discharge mode
When activating the discharge mode (ADAnDISC bit of ADAnM2 register is
set) the internal capacitors of the sample and hold circuit are discharged prior
to every conversion.
Additional 4 clocks must therefore be added to every conversion.
