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.
