ok thanks all for you help: I found a way to do that with the following code
:
;disable interruption request handling
;by writing 00000000,11011111 into the interrupt mask register
IMR equ $FFFFF304 ;Interrupt Mask Register
move.l #$ffffffff,IMR ; disable every interrupts
I need to do this because I try to measure the power consumption of a given
intruction of the instruction set. So I need to have this instruction
executed in an infinite loop without any interruption interrupting it.
so far it worked pretty well. I hope to developp a tool that wil evaluate
the power consumption (at the microprocessor level only) of a given program
