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

The I/O 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.

It is recommended that 1 to 10 k

Ω resistors be used when connecting to VDD or VSS via a resistor.
