37.6.7 ADC Trigger Concept – Use Case
FTM module support counter init trigger and channel match trigger, these triggers could
be used as trigger input of PDB, PDB then be used to trigger other modules like ADC.
Each ADC channel in PDB module supports up to 8 pre-triggers, which could be used as
ADC hardware channel selection to precondition the ADC block prior to actual trigger.
The ADC trigger is initiated after pre-trigger to trigger ADC conversion. The waveforms
shown in following diagram illustrate the pre-trigger and trigger output of PDB to ADC.
Every time when one PDB pre-trigger and trigger output starts an ADC conversion, an
internal lock associated with the corresponding pre-trigger is activated. This lock
becomes inactive when receiving COCO signal from ADC.
