Step
Comparator B1 and comparator B3 operate independently. Their operations are the same.
Table 31.3 lists the Procedure for Setting Registers Associated with Comparator B.
Figure 31.2 shows an Operating Example of Comparator Bi (i = 1 or 3).
If the analog input voltage is higher than the reference input voltage, the INTiCOUT bit in the INTCMP register
is set to 1. If the analog input voltage is lower than the reference input voltage, the INTiCOUT bit is set to 0. To
use the comparator Bi interrupt, set the INTiEN bit in the INTEN register to 1 (interrupt enabled). If the
comparison result changes at this time, a comparator Bi interrupt request is generated. Refer to 31.4
Comparator B1 and Comparator B3 Interrupts for details of interrupts.
Select the function of pins IVCMPi and IVREFi. Refer to 6.6 Port Settings .

Procedure for Setting Registers Associated with Comparator B
Operating Example of Comparator Bi (i = 1 or 3)
The above applies under the following conditions:
Bits INTiF1 to INTiF0 in INTF register = 00b (no filter)
INTiPL bit in INTEN register = 0 (both edges)
i = 1 or 3
Select whether to enable or disable the filter.
Select the sampling clock.
