10.Input/output current is excluded. When input is at an intermediate level with CMOS, the excessive
current flows through the input circuit to the power supply. To avoid this from happening, the input
level must be fixed high or low.

Since oscillation frequency varies depending on OSC1 and OSC2
terminal capacitance,wiring length to these pins should be minimized.
