Handling Of Unconnected Pads
Signal input stages may generate undesired switching noise and cross-current when left
open. Respect the following precautions for unconnected (not bonded) pads:

1)
The lower part of PORT1 (P1L) may be left open and its input stages can then be disabled via P1DIDIS.
2)
Port pad is input in this case! If the port pad is used, the corresponding alternate output pad may be left open.
3)
Pin RD can be used for configuration to disable the OWD. Otherwise it is held high by an internal pullup.
Input port pads
Double-bond ports
Disable input stages via P5DIDIS
Connect port pad (43, 46), if the
alternate output (44, 47) is used.
