I want to configure Port A as inputs. According to the schematic for the Mega board
(http://arduino.cc/en/uploads/Main/arduino-mega2560-schematic.pdf) the pin mapping shows PA1 to be connected to PIN 23 on the silkscreen mapping on the MEGA board.
On the PinMap2560 page (http://arduino.cc/en/Hacking/PinMapping2560), the pin mapping shows PA1 connected to PIN 15, which I believe is incorrect(Should be PIN 23). And by way of clarification, PINxx designations in this text refer to the silkscreen pin designations on the Arduino Mega board.
I did a continuity check from pin 77 on the Mega2560 IC to silkscreen PIN 23 ( on the board, and it checks.)
Would someone pls verify this?
