Notes:
1. x in the FRQCR register setting depends on the set value in bits 12 and 13.
2. The ratio of clock frequencies, where the input clock frequency is assumed to be 1.
3. In mode 0 or 1, the frequency of the EXTAL pin input clock or the crystal resonator
In mode 2, the frequency of the CKIO pin input clock.
In mode 3, the frequency of the USB_X1 pin input clock or the crystal resonator
Cautions: 1. The frequency of the internal clock is as follows:
In mode 0 the frequency on the EXTAL pin × the frequency-multiplier of the PLL
circuit × the divisor of the divider 1
In mode 1 (the frequency on the EXTAL pin × 1/2) × the frequency-multiplier of
the PLL circuit × the divisor of the divider 1
In mode 2 (the frequency on the CKIO pin × 1/4) × the frequency-multiplier of
the PLL circuit × the divisor of the divider 1
In mode 3 (the frequency on the USB_X1pin × 1/4) × the frequency-multiplier of
the PLL circuit × the divisor of the divider 1
The frequency of the internal clock should not be set lower than the frequency on the
CKIO pin.
