In the user manual for the 2106 it states that pins P0.29-31 have internal pullups. If I scope the line and drive it low only and then let it float high, my signal levels stay between 0 and about 2.2 volts. I expected the pullups to pull it up to VDD. Is there a setting in a register for this? Or is there really not a pullup? Rob
