Question

Assuming you have written a function called "MyHandler" to serve as the ISR for a GPIO interrupt, how could you get the address of this function stored into the handler vector table? Think back to your Assembly programming days. If you still need a hit, open any of your C projects in Keil and take a look at the "Startup MKL25Z4.s" file that is added to all new C projects by Keil. Every IRQ sources has an assigned IRQ number that is unique to each source. During the automated exception management process, where does this IRQ number get stored?

Explanation / Answer

To write the Myhandler as ISR the complier attribute is used while declaration and definition of Myhandler. The attribute is depends upon complier.

In Keil, 'using interrupt ' and than integer of interrupt which is natural priority.

The IRQ number is not stored anywhere. The IRQ is implement in digital logic.
