ADC conversion ADCDONEI, and one for the ADCBIS conversion ADCBISDONEI. These interrupts will go high after the
conversion, and can be masked.
conversion of the first request, an ADTRIG trigger event of the other request is ignored, if for the other request the TRIGMASK
bit was set to 1. When this bit is set to 0, the other request ADTRIG trigger event is memorized, and the conversion will take place
directly after the conversions of the first request are finished.
conversion has to be lined up to a periodically ADTRIG initiated conversion. In case of ASC initiated conversions, the TRIGMASK
bit is of no influence.
by setting the ADONESHOT bit to a one. In that case, only at the first following conversion, an ADTRIG trigger event is accepted.
ASC events are not affected by this setting. Before performing a new single shot conversion, the ADONESHOT bit first needs to
be cleared. Note that this bit is available for each of the conversion requests 'ADC' or 'ADC BIS', so can be set independently.
TRIGMASK setting. If both conversion requests have identical TRIGMASK settings, priority is given to the 'ADC' conversion over
the 'ADC BIS' conversion. Note that the ADONESHOT is also taken into account.
transition on the ADTRIG pin. The ADC completely ignores either ADTRIG or ASC pulses while ADEN is low. When reading
conversion results, it is preferable to make ADEN = 0.

There are two interrupts available to inform the processor when the ADC has finished its conversions, one for the standard
When two requests are queued, the request for which the trigger event occurs the first will be converted the first. During the
The following diagram shows the influence of the TRIGMASK bit. The TRIGMASK bit is particularly of use when an ADC
To avoid results of previous conversions getting overwritten by a periodical ADTRIG signal, a single shot function is enabled
It is possible to queue two ADTRIG triggered conversions. Both conversions will be executed with a priority based on the
To avoid that the ADTRIG input inadvertently triggers a conversion, the ADTRIGIGN bit can be set which will ignore any
