I/O symbols

• I:

Input

• Is:

Schmitt trigger input

• I+:

Built in pull-up circuit (*)

• O:

Output

• Ot:

3-state output

* Built in pull-up circuit cannot be used for Hi-level output of the LSI, because of this ability is only keep Hi-level for input pin

when it is open.

* The above resistor and capacitor values vary depending on a crystal oscillator.

Be sure to meet the

specifications for the crystal oscillator to be used.
