31. Comparator B
Comparator B compares a reference input voltage and an analog input voltage. Comparator B1 and comparator B3 are
independent of each other.

Selectable function
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 31.1 lists the Comparator B Specifications, Figure 31.1 shows the Comparator B Block Diagram, and Table
31.2 lists the I/O Pins.
