Does somebody know the LPC1114 pull up/down resistors value? I can't find this information anywhere. Thanks again!

The pull-up and pull-downs are not actual resistors. They are transistors configured as a current source. These are "weak" current sources. For simplicity we call it a resistors.

I think the pull-up is an active pull-up, not a passive resistor. There's no simple value (in ohms) for an active pull-up.

The pull-up/down is listed as a IV graph in the datasheet.  Base on the operating condition, you would get different values.
