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 the recommended connections of the unused pins. Figure

2-1 shows a partially simplified diagram of each circuit.

It is recommended that 1 to 10 kΩ resistors be used when connecting to V

DD or VSS via a resistor.
