LPC1227 GPIO current consumption

Hi guys,

I'm working with a LPC1227 which i enter in deep sleep mode. The issu appears when i want to keep GPIO0_20 as an output to high. In this case the current consumption is around 2.1mA.
On the other hand when i put this pin to LOW, the current consumpion is around 30uA.

This pin goes to nowhere cause i have lifted it up from the PCB, so it is astonishing.

Any help will be apreciated.

Thanks and best regards.

Alberto

I have also realised that this issue happens with all GPIOs which can work as input comparators.
Is anything special with this GPIOs that i have to do?

Any help will be apreciated

Thanks!
