ARM assembler register read

Note: This was originally posted on 11th September 2010 at http://forums.arm.com

Hello All,

I need a quick example of how to place a value from a hardware register (0x70001234 for example) into a register such as R0
then compare it to a constant such as 0xE0680003 and do a branch based on equality.

So far I have had no luck getting something this simple to work.

Thanks,
Dennis

Also note that in the ARM, program/data memory transactions are denoted by the bracket "[ ]".
On some processors, this is the parenthesis or the "@" sign.

Stack transactions are denoted by braces "{ }".

Well, as long as the machine code is correct, who cares? :-)
