which interrrupt priority is higher?
systick vs IRQ(external timer)
because In my case externl timer is higher then systick.
I saw that during processing in systick ISR, but suddenly pc jump to timer ISR
so I experimented print out. systick print letter is broken. but timer print is out correctely
I think that systick priority is higher than external timer
why this situation is occured?

so. I understood very much about priorities.
thank you~
With kind regards, yours
