Section 10 On-Chip Oscillation Circuits
The WDT has the following features:
• Can be used to ensure the clock settling time: Use the WDT to cancel standby mode and the
temporary standby which occur when the clock frequency is changed.
• Can switch between watchdog timer mode and interval timer mode.
• Generates internal resets in watchdog timer mode: Internal resets occur after counter overflow.
Selection of power-on reset or manual reset.
• Generates interrupts in interval timer mode: Internal timer interrupts occur after counter
overflow.
• Selection of eight counter input clocks. Eight clocks (×1 to ×1/4096) can be obtained by
dividing the peripheral clock.
