Lpc2000

Thank you very much!
That means if I want to enable p0.9 then i would write 0x00000200 
(0x0000 0000 0000 0000 0000 0010 0000 0000)...Am I right??

Then what for p1.25 or p3.4 or other pins? How would I initialize 
those pins in this way?

Would you please send me a link where it is already explained? 

Thank you.
