Table 4.2 shows the relationship between the combinations of the mode control pins (MD_CLK1
and MD_CLK0) and the clock operating modes. Table 4.3 shows the usable frequency ranges in
the clock operating modes.

In mode 0, clock is input from the EXTAL pin or the crystal oscillator. The PLL circuit shapes
waveforms and the frequency is multiplied according to the frequency control register setting
before the clock is supplied to the LSI. The oscillating frequency for the crystal resonator and
EXTAL pin input clock ranges from 10 to 16.67 MHz. The frequency range of CKIO is from
40 to 66.66 MHz. To reduce current consumption, fix the USB_X1 pin (pull up, pull down,
connect to power supply, or connect to ground) and open the USB_X2 pin when USB is not
used.
In mode 1, clock is input from the EXTAL pin or the crystal oscillator. The PLL circuit shapes
waveform and the frequency is multiplied according to the frequency control register setting
before the clock is supplied to the LSI. The oscillating frequency for the crystal resonator and
EXTAL pin input clock ranges from 20 to 33.33 MHz. The frequency range of CKIO is from
40 to 66.66 MHz. To reduce current consumption, fix the USB_X1 pin (pull up, pull down,
connect to power supply, or connect to ground) and open the USB_X2 pin when USB is not
used.
