52.6.9 Offset Compensation
The Swap bit in the Comparator Control registers (COMPCTRLn.SWAP) controls switching of the
input signals to a comparator's positive and negative terminals. When the comparator
terminals are swapped, the output signal from the comparator is also inverted, as shown in
the following figure.
Note: The output signal from the comparator is
inverted only if the comparator inputs difference is within offset values.
This
allows the user to measure or compensate for the comparator input offset voltage. As part
of the input selection, COMPCTRLn.SWAP can be changed only while the comparator is
disabled.
