Lpc2000

My 2 cents:

Mukund,
Unfortunately there is seperate control over set and clear of GPIO 
in the LPC 2XXX .. my initial guess is that this is not slam dunk as 
you would expect it to be. You might have to rummage through the 
code to see if you are setting the bits or clearing it and then 
modify that line as required. 
Tedious and unfortunate ...
