12.5.9
The CKIO pin can be switched between clock output and the high-impedance state by means of
the CKOEN bit in FRQCR. When the CKIO pin goes to the high-impedance state, it is pulled up.

(1) Using a crystal resonator
Place the crystal resonator and capacitors CL1 and CL2 close to the EXTAL and XTAL pins. To
prevent induction from interfering with correct oscillation, ensure that no other signal lines cross
the signal lines for these pins.
(2) Inputting external clock from EXTAL pin
Make no connection to the XTAL pin.
(3) Using a PLL oscillation circuit
Separate VDD-CPG and VSS-CPG from the other VDD and VSS lines at the board power supply
source, and insert resistors RCB and RB and bypass capacitors CPB and CB, close to the pins.

Usage Notes
Note: The values for CL1, CL2, and the damping resistance should be determined after
