There is also a comparator block responsible for the thermal shutdown (TSHUT) function of the thermal management logic. This comparator block is also composed of two comparators. One dedicated to COLD TSHUT threshold and the other one to high TSHUT threshold.
The comparator outputs for the high TSHUT thresholds of each sensor are ORed and used to generate a single EVNT_TSENSE_CRITICAL error signal to ESM.The comparator outputs for the high and low TSHUT thresholds are used to generate TSHUT_RST0 pulse signal which asserts when high TSHUT is active and deasserts when low TSHUT is active. TSHUT_RST* signasl from both sensors are routed as warm reset source to reset the chip.
The TSHUT_HOT and TSHUT_COLD threshold values are by default controlled from EFUSE. TOP_CTRL.TSENSE*_TSHUT registers can be used to override the value from EFUSE and apply the same from the bit fields of TOP_CTRL.TSENSE*_TSHUT registers.
