Comparator B generates an interrupt request from two sources, comparator B1 and comparator B3. The
comparator Bi (i = 1 or 3) interrupt uses the same INTiIC register (bits IR and ILVL0 to ILVL2) as the INTi (i
= 1 or 3) and a single vector.
To use the comparator Bi interrupt, set the INTiEN bit in the INTEN register to 1 (interrupt enabled). In
addition, the polarity can be selected by the INTiPL bit in the INTEN register and the POL bit in the INTiIC
register.
Inputs can also be passed through the digital filter with three different sampling clocks.
