When Using Crystal Resonator: Place the crystal resonator and capacitors 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.
When Inputting External Clock from EXTAL Pin: Make no connection to the XTAL pin.
When Using PLL and DLL circuit: Separate each VDD-PLL, VDD-DLL, VSS-PLL, and VSS-
DLL from the other VDD and VSS lines at the board power supply source, and insert resistors
(RCB and RD) and bypass capacitors (CPB and CD) close to the PLL and DLL pins as noise
filters.
