Notes:
1. The ratio of clock frequencies, where the input clock frequency is assumed to be 1.
2. In modes 2 and 6, the frequency of the clock input from the EXTAL pin or the
frequency of the crystal resonator. In mode 7, the frequency of the clock input from
the CKIO pin.
Caution: 1. The frequency of the internal clock is the frequency of the signal input to the CKIO
pin after multiplication by the frequency-multiplier of PLL circuit 1 and division by the
divider's divisor. Do not set a frequency for the internal clock below the frequency of
the signal on the CKIO pin.
2. The frequency of the peripheral clock is the frequency of the signal input to the CKIO
pin after multiplication by the frequency-multiplier of PLL circuit 1 and division by the
divider's divisor. Set the frequency of the peripheral clock to 33.33 MHz or below. In
addition, do not set a higher frequency for the internal clock than the frequency on
the CKIO pin.
3. The frequency multiplier of the PLL circuit can be selected as x1, x2, x3 or x4. The
divisor of the divider can be selected as x1, x1/2, x1/3 or x1/4. The settings are made
in the respective frequency-control registers.
4. The signal output by PLL circuit 1 is the signal on the CKIO pin multiplied by the
frequency multiplier of PLL circuit 1. Ensure that the frequency of the signal from PLL
circuit 1 is no more than 100 MHz.
