Hi everyone:

I just begin to study ARM assembly language, and am not clear about how to use MOV to transfer an immediate number into a register.

From both the ARM reference manual and my textbook, it's said that range of immediate number following MOV instruction is 0-255. But when I test on my own PC in ADS 1.2 IDE, instruction

MOV     R2, #0xFFFFFFFF

performs well. Isn't number 0xFFFFFFFF out of range according to the specification?

Hope someone can give me a hand.

Regards.
