1. Use the CKIO frequency within 33.34 MHz ≤ CKIO ≤ 66.67 MHz.
2. The input to divider 1 is the output of PLL circuit 1.
3. Use the internal clock frequency within 33.34 MHz ≤ Iφ ≤ 133.34 MHz.
4. Use the peripheral clock frequency within 8.34 MHz ≤ Pφ ≤ 33.34 MHz.
5. × 1, × 2, × 3, or × 4 can be used as the multiplication ratio of PLL circuit 1. × 1, × 1/2,

Maximum frequency: Iφ = 133.34 MHz, Bφ (CKIO) = 66.67 MHz, Pφ = 33.34 MHz
The internal clock frequency is the product of the frequency of the CKIO pin, the
frequency multiplication ratio of PLL circuit 1 selected by the STC bit in FRQCR, and
the division ratio selected by the IFC bit in FRQCR.
Do not set the internal clock frequency lower than the CKIO pin frequency.
The peripheral clock frequency is the product of the frequency of the CKIO pin, the
frequency multiplication ratio of PLL circuit 1 selected by the STC bit in FRQCR, and
the division ratio selected by the PFC bit in FRQCR.
Do not set the peripheral clock frequency higher than the frequency of the CKIO pin.
× 1/3, or × 1/4can be selected as the division ratio of an internal clock. × 1, × 1/2, × 1/3,
× 1/4, or
× 1/6 can be selected as the division ratio of a peripheral clock. Set the rate in FRQCR.
