Fault Queue
The EMC2101 supports a Fault Queue feature to reduce interrupts caused by spurious temperature
readings. This feature, (see Section 6.5), will not trigger an interrupt until the device has measured
three consecutive out-of-limit HIGH, LOW, or T_CRIT temperature readings. Figure 5.8 shows an
example of this behavior. The Fault Queue only applies to the External Diode channels.
