    2.3 Pin I/O Circuits and Recommended Connection of Unused Pins
    Table 2-1 shows the I/O circuit type of each pin and recommended connection of unused pins. Figure 2-1 shows
    the various circuit types using partially abridged diagrams.
    When connecting to V
    DD
    or V
    SS
    via a resistor, a resistance value in the range of 1 to 10 k
    is recommended.
