Note: * Taking input clock as 1
Cautions:
1. The input to divider 1 is the output of the PLL circuit 1:
2. The input of divider 2 is the output of the PLL circuit 1.
3. The frequency of the internal clock (I ):
4. The frequency of the peripheral clock (P ):
5. The output frequency of PLL circuit 1 is the product of the CKIO frequency and the

and
control register. The on/off state of PLL circuit 2 and the multiplication ratio are determined by
the mode.

When PLL circuit 1 is on.
The frequency of the internal clock (I ) is the product of the frequency of the CKIO
pin, the frequency multiplication ratio of PLL circuit 1, and the division ratio of divider
1 when PLL circuit 1 is on.
Do not set the internal clock frequency lower than the CKIO pin frequency.
The frequency of the peripheral clock (P ) is the product of the frequency of the CKIO
pin, the frequency multiplication ratio of PLL circuit 1, and the division ratio of divider 2.
The peripheral clock frequency should not be set higher than the frequency of the CKIO
pin, higher than 33 MHz, or lower than 1/8 the internal clock (I ).
