the standby mode to be reduced. Note that even in the shutdown mode it is possible to set up T
and to read the data from or write the data in the Configuration register.
The next chart illustrates the timing of temperature detection operation when the O.S polarity is in the Active
In order to avoid faulty detection in noisy environment, it is possible to set multiple numbers of detections of
