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, and depends on the time set in the wait control registers corresponding to the oscillators.
Note 2. The indicated value is measured for an 8 MHz crystal resonator. ICLK is set to divided by 1.
Note 3. When RCR3.RTCEN = 1, the time will be the time set in the SOSCWTCR register minus 2 s.
Note 4. When the external clock frequency is 20 MHz. ICLK is set to divided by 1.
Note 5. ICLK is set to divided by 1.
Note 6. When the frequency is 50 MHz, HOCOWTCR2.HSTS2[4:0] = 10101b and ICLK is set to divided by 2.
When the frequency is 32 MHz, HOCOWTCR2.HSTS2[4:0] = 10100b and ICLK is set to divided by 1.
