I simply want to toggle MP0 pin high (+3.3V) and low (0V) from Sigma Studio. I have connected a voltage meter between Pin 2 (gnd) and pin 3 (MP0) on the ADAU1442 evaluation board 50-pin header but no matter what I do, the MP0 pin stays high (+3.3V).
Am I doing something wrong?
Earlier I successfully used one of the MP pins as input and it worked fine. But I cannot get any of the MP pins to work as an output, they stay fixed at +3.3V.
