help with MCU CC2430

Hey,
I have a CC2430 MCU, and i connected a switch button to the pin P1_1 of the MCU, so every time i press the button, it applies 3.3VDC on P1_1.
I would like to execute a certain command each time P1_1 is rising from LOW (0V) to HIGH (3.3V), but i dont know how to do it.
I've read in the datasheet (page 50) that the Interrupt Vector is 0x7B, but when I placed a breakpoint in the code that were placed in that address, the program didnt stop in there when i pressed the button.

Does someone have an experience with the CC2430, and maybe could help me with it?

Here is a link to the datasheet of the CC2430:

Thanks.

Don't know about that particurlar chip, but with the 8051 it would look like this

SETB EA; enable all interrupts
SETB IT0 ; edge activated
SETB EX0 ; enable external interrupt 0

Your chip has EA and IT0, so it might be similiar.

Thanks.
Why do you take into account the EI0 here?
or it was only as an example?

What's EI0?

External interrupt zero.

You've lost me.
Do you mean IE0? There's nothing called EI0 to the best of my knowledge.

I was just sparing words here, "SETB EX0 ; enable external interrupt 0", i meant that.
