7.3.6 ALERT and THERM Functions
The operation of the ALERT (pin 6) and THERM (pin 4) interrupts is shown in Figure 7-2. The operation of the THERM (pin 4) and THERM2 (pin 6) interrupts is shown in Figure 7-3.

THERM Interrupt Operation
Figure 7-3 THERM and
THERM2 Interrupt OperationThe hysteresis value is stored in the THERM hysteresis register. The value of the CONAL[2:0] bits in the consecutive ALERT register determines the number of limit violations before the ALERT pin is tripped. The default value is 000b and corresponds to one violation, 001b programs two consecutive violations, 011b programs three consecutive violations, and 111b programs four consecutive violations. This provides additional filtering for the ALERT pin state.
