• SELPLUS: SELection for PLUS comparator input
0..7 = selects the input to apply on analog comparator SELPLUS comparison input.
• ACEN: Analog Comparator ENable
0 (DIS) = Analog Comparator Disabled.
1 (EN) = Analog Comparator Enabled.
• EDGETYP: EDGE TYPe
• INV: INVert comparator output
0 (DIS) = Analog Comparator output is directly processed.
1 (EN) = Analog Comparator output is inverted prior to being processed.
• SELFS: SELection of Fault Source
0 (CF) = the CF flag is used to drive the FAULT output.
1 (OUTPUT) = the output of the Analog Comparator flag is used to drive the FAULT output.
• 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.
