HI:

When I configure the BACK-TO-BACK mode of PDB, can I only configure channels 0-7 in sequence, but not remove channels from the middle ?

Thanks

Hi 

Please read the "46.1.3 Back-to-back acknowledgement connections" and "Figure 46-5. PDB-ADC back to back con": Back-to-back operation enables the ADC conversions complete to trigger the next PDB channel pre-trigger and trigger output.

There is no such possibility that Pre-trigger 0 COCO is directly connected to Pre-trigger 2.
