Hi Anthony,
I got a strange problem. I want use GIOB[2] as a input. But I can not got the value of this pin.
For GIOB[2], I have gated off the Emif_CLK in HCG(HALCoGen 03.05.02). I changed the level of the pin through hardware and read the value by the code showed below, but it did not change. Because this is a specific, I maybe make some mistakes.
Would you help me to find the problem.
