This register configures the fault detection operation.

Bits[7:5] COMP_TH[2:0]: Fault detect comparator threshold

These bits determine the fault detect comparator threshold level setting. See the Fault Detection section for a detailed

description.

Comparator high-side threshold

000 = 95% (default)

001 = 92.5%

010 = 90%

011 = 87.5%

100 = 85%

101 = 80%

110 = 75%

111 = 70%

Comparator low-side threshold

000 = 5% (default)

001 = 7.5%

010 = 10%

011 = 12.5%

100 = 15%

101 = 20%

110 = 25%

111 = 30%

Bits[4:0] Must be set to '0'
