I use an LPC1778 LQFP144</pre>
<pre>I set up the following pins as digital inputs:

P0[7]
P0[8]
P0[9]

I have 3.3 V on the pins but I only read '0's from the PIN register. I've tried to activate the internal pull-up with but the result was the same. 
These pins are of type W does this have an impact? I've used type D pins as digital inputs without encountering any problem.
