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 CxPOL bit. Clearing the CxPOL bit results in a non-inverted output.

Table 1 shows the output state versus input conditions, including polarity control.

Table 1. Comparator Output State vs. Input Conditions
Input Condition CxPOL CxOUT
CxVn > CxVp 0 0
CxVn < CxVp 0 1
CxVn > CxVp 1 1
CxVn < CxVp 1 0
