Note) 1. The CPU uses the clock output from the oscillation circuit as the operating clock.
2. When an external clock is input from the OSC3 terminal by setting the mask option, do not connect anything to the OSC4 terminal.
3. The values enclosed with ( ) indicate the execution time when the CR oscillation circuit is used.
