Handling of I/O Pins Not Used by User System
If I/O pins that are not used by the user system are left floating, they may generate noise that can result in
chip malfunctions. Therefore, the pin potential must be fixed.
In this case, pull the pins up to V
CC
with the built-in pull-up MOS or with an external resistor of
approximately 100 k
