Exceeding any of the temperature limits shown in Table 35 by 1°C causes the appropriate status bit to be set in the interrupt status registers.
High limits: An interrupt is generated when a value exceeds its high limit (> comparison).
Low limits: An interrupt is generated when a value is equal to or below its low limit (≤ comparison).
