Yeah, thanks. But it does not say whether it can be seen by software programmers or not (so I can not find pc register). Excuse me, I have no any more experience for other architectures (only know about x86), so after read Section 3.4, I originally misunderstood lr is pc. When I know I can not see/find pc, I want to get confirmation. Thanks. -- Chen Gang Open, share, and attitude like air, water, and life which God blessed
