Watchdog timer 2 has the following functions.
• Default-start watchdog timer
• Input from main clock, internal oscillation clock, and subclock selectable as the source clock
→ Reset mode: Reset operation upon overflow of watchdog timer 2 (generation of WDT2RES signal)
→ Non-maskable interrupt request mode: NMI operation upon overflow of watchdog timer 2 (generation of
Notes 1. Watchdog timer 2 automatically starts in the reset mode following reset release.
