5.2.7. Temperature OVT# Signal
There is a mode of temperature (t1 to t4) OVT function, and refer t1 to t4 temperature in
the below Figure.
Over temperature event will trigger OVT# that shown as figure 3. In hysteresis mode,
when monitored temperature exceeds the high temperature threshold value, OVT# will be
asserted until the temperature goes below the hysteresis temperature.

5.2.8. Temperature PME#
PME# interrupt for temperature is shown as figure 4. Temperature exceeding high limit
(low limit) or going below high hysteresis (low hysteresis) will cause an interrupt if the
previous interrupt has been reset by writing “1” all the interrupt Status Register.
