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