*11 The clock duty ratio should be 45% to 55%
*12 _{Rising time and falling time differ depending on the oscillation frequency.}
The max value is not a specified value but a rough value.
Please consult the oscillator manufacturer and perform matching tests enough for determining appropriate
values.
