Hi
About the assumption of S32K144, I'm confused about how to implement it.
Assumption: [SM_084] The application software must check the status registers of the RCM for error flags.
In my understanding, I shall read the reset source when power on, but if it is right, what can I do when get the reset source? reset again? or just warning to driver?
Can you give me more information about this? Thanks!
The RM refers to AN4503: Power Management for Kinetis and ColdFire+ MCUs
The RCM_SRS register simply indicates the source of the most recent reset.
This allows handling each reset differently.
For example, RCM_SRS[WDOG] is can be used for identifying WDOG reset during WDOG testing:
Example S32K116 WDOG Fast Test
