38.2.3 Comparator Output Polarity

Inverting the output of the comparator is functionally equivalent to swapping the comparator inputs. The polarity of the comparator output can be inverted by setting the POL bit. Clearing the POL bit results in a noninverted output. Table 38-1 shows the Output state versus Input conditions, including polarity control.

Table 38-1. Comparator Output State vs. Input Conditions
Input ConditionPOLOUT
CxVn > CxVp00
CxVn < CxVp01
CxVn > CxVp11
CxVn < CxVp10
Important: The POL bit may only be changed when the comparator is disabled (EN = 0).
