... a few registers.
If you are NOT using the crossbar, then you can ignore the P2SKIP (Port2 Skip) register. Then you need to do two things. First, clear (ensure it's 0) bit 6 in the P2MDOUT (Port2 Output Mode) register, which puts P2.6 into open drain mode. Then ensure that bit 6 in P2MDIN (Port2 Input Mode) is SET (ensure it's a 1). This ensures that P2.6 is NOT configured as an analog input. Because, if one RTFDS, one sees (on p136) that if P2MDIN.6 is cleared (zero), then when you read P2.6, you'll always read back a 1.
