Other Parts Discussed in Thread: MSP430FR5969
Hello,
I would like to know about some question about PMM29 errata on MSP430fR6877.
I am considering implementing workaround 3 for PMM29.
And I would like to use watch dog timer.
But according the Note, it is described that if the WDT triggers PUC reset during LPM2/3/4, workaround 3 doesn't make sense and lockup will occur.
Could you confirm about following question?
1.I understood that I should only pay attention to WDT triggers because all other PUC triggering factors do not occur during LPM. Is my understanding correct?
2.If I followed Note about workaround 3 and the program hangs during an interrupt other than the WDT interval timer interrupt, I think that it cannot be reset by the WDT interval timer interrupt unless nested interrupt are enabled.
Is my understanding correct?
If yes, Is there a way not to enable nested interrupt but reset the hang of the program during interrupt processing in workaround3 case?
Regards,
U-SK
