Legend:
Note 1:
2:
VIRV = Fixed Interval Reference Voltage (1.2V nominal), CVREF = Comparator Voltage Reference module output.
Configurations are available on both Comparators 1 and 2 in all package sizes unless otherwise noted.
Configuration is available in 80-pin devices only.
Configuration is available in Comparator 2 only (80-pin devices).
