To remedy this ambiguity in the TSE2002av specification, one must avoid setting both bit two and three of the
Configuration register to Logic 1 concurrently. Instead, bit two should be set first before bit three in separate commands
to offer universal compatibility if the system is designed to only trigger off the Critical Alarm temperature threshold.
Please see the Atmel Application Note, “Utilizing a Digital Temperature Sensor in a DDR3 DIMM,” for more details.
