Exceeding any of these temperature limits by 1°C causes the appropriate status bit to be set in the Interrupt Status Register. Setting the Configuration Register 1 Lock
bit has no effect on these 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).
