If the die temperature exceeds the trip point of the thermal warning (TOTW), the OTW bit is set in the registers of the SPI device. The device performs no additional action and continues to function. When the die temperature decreases below the hysteresis point of the thermal warning, the OTW bit clears automatically. The OTW bit can also be configured to report on the nFAULT pin by setting the OTW_REP bit to 1b through the SPI registers.
