10. Clock Oscillation Circuits
The WDT has the following features
• Can be used to secure clock stabilization time
• Can be switched between watchdog timer mode and interval timer mode
• Internal reset generation in watchdog timer mode
• Interrupt generation in interval timer mode
• Selection of eight counter input clocks
The CPG is described in sections 10.2 to 10.6, and the WDT in sections 10.7 to 10.9.

REJ09B0370-0400
Used when exiting standby mode or a temporary standby state when the clock frequency is
changed.
An internal reset is executed on counter overflow.
Power-on reset or manual reset can be selected.
An interval timer interrupt is generated on counter overflow.
Any of eight clocks can be selected, scaled from the ×1 clock of frequency divider 2 shown in
figure 10.1.
