6.5.3.2. Interrupt Mode:
At this mode, temperature exceeding T_O causes the OVT# output activated indefinitely until reset by
reading interrupt status register. Temperature exceeding T_O, then OVT# asserted, and then
temperature going below T_HYST will also cause the OVT# activated indefinitely until reset by reading
temperature sensor1 or sensor2 registers. Once the OVT# is activated by exceeding T_O, then reset, if
the temperature remains above T_HYST, the OVT# will not be activated again. (Figure 5)

6.5.4 Temperature Fault (Temp_fault #)
W83L785R/G provides a good protection for temperature. Setting pin11 (TEMP_FAULT#) to monitor
temperature and enable TEMP_FAULT# function. When VTIN1 (Pin19) or VTIN (Pin18) temperature
exceeds Temperature fault limit in CR53,or R54 pin11 TEMP_FAULT# will be asserted. (Figure 6)
