Bit 14 – FE Fault Enable
0 (DIS): The FAULT output is tied to 0.
1 (EN): The FAULT output is driven by the signal defined by SELFS.
Bit 13 – SELFS Selection Of Fault Source
0 (CE): The CE flag is used to drive the FAULT output.
1 (OUTPUT): The output of the analog comparator flag is used to drive the FAULT output.
Bit 12 – INV Invert Comparator Output
0 (DIS): Analog comparator output is directly processed.
1 (EN): Analog comparator output is inverted prior to being processed.
