The ARM7 is a well documented processor. For the answer to your question, try section 2.8 in the technical reference manual here:

http://infocenter.arm.com/help/topic/com.arm.doc.ddi0210c/DDI0210B.pdf

It's a great resource for lots of questions on the ARM. I have read much of it, and I refer to it especially when I have a question about exceptions, or about the assembly language.
