2.3 I/O Circuits of Pins and Recommended Connections 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.

When connecting a pin to VDD or VSS via resistor, use of a resistor of 1 to 10 kΩ is recommended.
