D6 STEP_VREF_MARGIN_LOW
Applies a fixed negative offset to the reference voltage. Adjustment is -20% to 0% in
2mV steps. Permissible values range between -120mV and 0mV) The offset is
calculated as (STEP_VREF_MARGIN_HIGH + VREF_TRIM)x2
-9
.Exponent fixed at -9(dec).
Net output voltage includes VREF_TRIM adjustment and ranges from -30% to 10%
