Note 1. The recovery time varies depending on the state of each oscillator when the WAIT instruction is executed. The recovery time
when multiple oscillators are operating varies depending on the operating state of the oscillators that are not selected as the
system clock source. The above table applies when only the corresponding clock is operating.
Note 2. When the frequency of crystal is 20 MHz.
When the main clock oscillator wait control register (MOSCWTCR) is set to 04h.
Note 3. When the frequency of the external clock is 20 MHz.
When the main clock oscillator wait control register (MOSCWTCR) is set to 00h.
Note 4. When the frequency of PLL is 40 MHz.
When the main clock oscillator wait control register (MOSCWTCR) is set to 00h.
