Hello, I have been reading the details concerning interrupt handling in the ARM core. I see how nested/not nested interrupts work, and that it is important to clear the interrupt in the handler to prevent an infinite loop. I see the assembly instruction for that, too. But why don't I see something similar when I compile the code for a C166? What did I miss?
Thanks in advane, Cactus Blip
What did I miss?
How one particular interrupt controller works is described in its documentation (different ARM7 chips may even have different interrupt controllers). Using one interrupt controllers documentation to make guesses about how a different controller works is fairly pointless.
Hello, That is true - I guess that's why I am called Cactus Blip :) :) :) In other words - curiosity.
