Notes: 1. The RES, NMI, and IRQ7 to IRQ0 signals are asynchronous signals. When the setup
time is satisfied, a signal change is detected at the rising edge of the clock signal. When
the setup time is not satisfied, a signal change may be delayed to the next rising edge.
2. In standby mode, t = t (10 ms). When changing the clock multiplication, t = t
