ARM926 Interrupt exception

Note: This was originally posted on 27th August 2009 at http://forums.arm.com

Hi,

I would like to program an interrupt handler for ARM926ej.

According to reference, when CPU is interrupted, it jumps to address 0xFFFF0018 (interrupt vector).

Then, I suppose I have to program a jump instruction to my handler in that address. But I don't know how.

I'm using GNU toolchain.

Thank you very much
Ricardo

You could keep a table of target addresses after your vector table. Then use a PC relative LDR to access it...

LDR pc, [pc, #???]
