Hi all,
1, AfterNMI interrupt happened , when software read NTSR register, it will found IB bit is 1. that means interrupts were blocked. What does interrupt were block mean? could you please provide some details?
2, After NMI interrupt processed, program return main loop, sometimes it will execute logic error. The datasheet said there some conditions it will not able to return normally. But if we want to use exception record function how to ensure NMI return normally?
3, We have found SPLOOP exception occurred but NTSR register SPLX bit have not been set to 1. why this happened?
thanks!
BR,
Denny
