In either window or traditional comparator mode, the comparator can be configured to latch after being asserted
by the COMP_LAT bit in the Config register. This setting causes the assertion to remain even if the input signal
is not beyond the bounds of the threshold registers. This latched assertion can only be cleared by issuing an
SMBus alert response or by reading the Conversion register. The ALERT/RDY pin can be configured as active
high or active low by the COMP_POL bit in the Config register. Operational diagrams for both the comparator
modes are shown in Figure 13.
The comparator can also be configured to activate the ALERT/RDY pin only after a set number of successive
readings exceed the threshold values set in the threshold registers (Hi_thresh and Lo_thresh). The
COMP_QUE[1:0] bits in the Config register configures the comparator to wait for one, two, or four readings
beyond the threshold before activating the ALERT/RDY pin. The COMP_QUE[1:0] bits can also disable the
comparator function, and put the ALERT/RDY pin into a high state.
