From here, looks like gpio 0-1 is always 13'h1803
and the gpio 2-4 is always GPIO_MODE_MGMT_STD_INPUT_NOPULL
From the gpio wrapper shown here, it appears that management input mode also generates a user input.Xiaochen Ni

which we force everyone to modify from invalid defaults so that we know everyone has at least looked at it and given it some consideration. That said, I'm not certain what our policy was at the time of the 2206Q tapeout.
For analog pads, the definitions in user_defines.v
for pins 14 to 24 simply have no effect, because there is no GPIO pad at those locations.Xiaochen Ni
