When Tdie >= tdie_shdn_off + tdie_shdn_hys , 9027LP-R will shut down.

When Tdie < tdie_shdn_off, die temperature shutdown function is OFF; however 9027LP-R may send EPT to shut down P9235A-R.

If tdie_shdn_off > Tdie > tdie_shdn_off - 10°C , 9027LP-R will send EPT because of die temperature.

If Tdie < tdie_shdn_off - 20°C, no EPT will be sent because of die temperature.
