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:

Standard IO pads
Switch to output
PORT0, PORT11), P2, P3,
P4, P6, P7, P8
1) The lower part of PORT1 (P1L) may be left open and its input stages can then be disabled via P1DIDIS.
Input port pads
Disable input stages via P5DIDIS P5
Double-bond ports
Connect port pad (43, 46), if the
alternate output (44, 47) is used.2)
2) Port pad is input in this case! If the port pad is used, the corresponding alternate output pad may be left open.
