CONFIGURATION REGISTER
Notes:
(1) Can not be written as long as either one of the two lock bits (D6 or D7) is set.
(2) The actual cause of an event can be determined by reading the temperature value registers. Interrupt events can be cleared by writing to
(3) Writing to this bit has no effect in comparator mode. When read, this bit always returns 0. Once the DUT temperature is greater than the
(4) Cleared at power-on reset (POR). Once set, this bit can only be cleared by a POR condition.
(5) When the device is shut down, both the band-gap and the ADC are disabled to save power, and no events are generated. Attempts to
