Wrong thresholds definition in trimming
The two thresholds are swapped in the text about the trimming.
“One value is the CFG_THR_ARM_DAC and the other is the CFG_THR_ZCC_DAC. The later must be calibrated for proper channel trimming; the former is of little concern since this is not used in either arming or CFD comparator modes. For more details on comparator voltage settings see the VFAT3 manual.“
