The comparison result of the reference input voltage and analog input voltage can be read by software. An input to
the IVREFi (i = 1 or 3) pin can be used as the reference input voltage.
Table 30.1 lists the Comparator B Specifications, Figure 30.1 shows a Comparator B Block Diagram, and Table
30.2 lists the I/O Pins.
