1. POR085_c and POR096_c threshold are untrimmed value, before the completion of the power-up sequence. All other
LVD/HVD thresholds are provided after trimming.
2. LV internal supply levels are measured on device internal supply grid after internal voltage drop.
3. LV external supply levels are measured on the die size of the package bond wire after package voltage drop.
