2.3 Pin I/O Circuits and Recommended Connection of Unused Pins

The input/output circuit type of each pin and recommended connection of unused pins are shown in Table 2-1.

Figure 2-1 illustrates the various circuit types using partially abridged diagrams.

When connecting to VDD or VSS via a resistor, a resistance value in the range of 1 to 10 kΩ is recommended.
