+description:
+ i.MX91 features a new temperature sensor. It includes programmable
+ temperature threshold comparators for both normal and privileged
+ accesses and allows a programmable measurement frequency for the
+ Periodic One-Shot Measurement mode. Additionally, it provides
+ status registers for indicating the end of measurement and threshold
+ violation events.
