   @davids5 Thanks for your input. We got into this due to a very costly ISR for the DW1000 during compliance. The unmodified ISR takes much longer than the conversion of four ADC channels. The FIFO itself already resolved our situation. So haven't had to think about throttling the interrupt rate. 
   Since this was a compliance related issue which required some extra stress, we expect that things are much calmer in the field.
