How to configure SODIMM56 in PXA320 as and GPIO input

I would like to use SODIMM56, SODIMM70 and SODIMM80 of PXA320 as and GPIO input. I have noticed problems. GPIO16_2, GPIO7_2 and GPIO12_2 does not work like the others GPIO. How to configure them as an input? Is it possible?

I have solved this problem. I have used GetPinLevel instead of GetGPIOLevel and now it works fine.

Hello @Konrad ,
can you suggest how to use GPIO as PWM input (Pin 30 and 67) or read the data from rotary encoder.
