I'm writing a small assembly routine to read the clock counter (CCNT) from 
my Pocket PC (PXA270 processor).

I used the following assembly code:
MRC p14, 0, R0, c1, c1, 0

Unfortunately, all I got was a constant number (548772751) while it
was supposed to change over time.

What's wrong? Please help me.

Thanks sincerely,
ARINTEL
