i have a question regarding to the nested interrupt function of the F105.
- I have 3 Interrupts with different priorities
- CAN bus rx has the lowest priority (highest number) and i want to parse the rx message directly in the CAN callback (so this could take a little bit of time)
So, what happens if the CAN bus callback is stopped because a interrupt with a higher priority is active and while this a new message arrives via the CAN Hardware ?
Is the controller clever enough that, when the controller jumps back into the CAN callback (number 1) it works with the first can message ?
And then a CAN callback (number 2) is called and the second message is on the gun ?
Or is this a bad situation ? Would be great if one of the interrupt specialist could give a hint about this situation...
Thanks in advance,
