1. Clear the WT/IT bit in the WTCSR register to 0, set the type of count clock in the CKS2–
2. Set the TME bit in WTCSR to 1 to start the count in interval timer mode.
3. When the counter overflows, the WDT sets the IOVF flag in WTCSR to 1 and an interval

When Using an External Crystal Resonator: Place the crystal resonator, capacitors CL1 and
CL2, and damping resistor R close to the EXTAL and XTAL pins. To prevent induction from
interfering with correct oscillation, use a common grounding point for the capacitors connected to
the resonator, and do not locate a wiring pattern near these components.
Decoupling Capacitors: Insert a laminated ceramic capacitor of 0.01 to 0.1 F as a passive
capacitor for each V
pins, and use components with a frequency characteristic suitable for the chip’s operating
frequency, as well as a suitable capacitance value.

When Using a PLL Oscillator Circuit: Keep the wiring from the PLL V
pattern to the power supply pins short, and make the pattern width large, to minimize the
