LESENSE with VLP as input to ACMP

I can't seem to get the ACMP to function properly when used in LESENSE (configured as MUXTHRES mode) with the negative input of the comparator connected to VLP (the positive input of the comparator is connected externally via APORT). I'm driving VLP from VADIV and then having LESENSE control DIV0/1 of VADIV, but those divider settings don't change the comparator threshold levels at all. However, when I instead connect the negative input directly to VADIV instead of VLP, the divider settings works as they should.

 

Is VLP unusable as a comparator input when LESENSE controls the ACMP?

Hi @gator_chomp,

 

Which MCU are you using?
