> For bits other than A0 Does this mean that A0 is producing correct results now? > Also tried with A1 - A6 ports How (exactly) did you try the other ports? Did you set both INCH and the relevant AE0 bit? P1.1-2 are used by the USB-UART through the RXD/TXD jumpers on the "bridge" header (J101). P1.3 is connected to a pushbutton, which (depending on which Launchpad you have) may or may not have a pullup resistor connected. What is your input source? SHT=0 is pretty short if your source isn't fairly low impedance.
