10.1 Functions
The watchdog timer has the following operation modes.
• Watchdog timer
• Interval timer
• Selecting the oscillation stabilization time
The following functions are realized from the above-listed operation modes.
• Generation of non-maskable interrupt request signal (INTWDT) upon overflow of watchdog timer
• Generation of system reset signal upon overflow of watchdog timer
• Generation of maskable interrupt request signal (INTWDTM) upon overflow of interval timer
• Securing of oscillation stabilization time for main system clock
Remark
Select whether to use the watchdog timer in the watchdog timer mode or the interval timer mode using
watchdog timer mode register (WDTM).
