6.5.3.2. Interrupt Mode:

At this mode, temperature exceeding TO causes the OVT# output activated indefinitely until reset by

reading interrupt status register. Temperature exceeding TO, then OVT# asserted, and then

temperature going below THYST will also cause the OVT# activated indefinitely until reset by reading

temperature sensor1 or sensor2 registers. Once the OVT# is activated by exceeding TO, then reset, if

the temperature remains above THYST, 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)
