Seth: I don't think the software commands can see any closer to the pins than the I/O registers associated with the pins. Physical or electrical damage to the pins, such as damaging the ESD diodes, or damaging an I/O transistor might not change the behavior at the I/O registers. If you want to test or verify the pin hardware, I think some minimal external hardware needs to be involved. --- Graham
