2.3 I/O Circuits of Pins and Processing of Unused Pins

Table 2-1 lists I/O circuit type of respective pins and processing method (recommended connection method) when

not used. 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.
