help with MCU CC2430

[rainman1]

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?

 

[colin mac]

What's EI0?

 

[rainman1]

External interrupt zero.

 

[colin mac]

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.
