11.1 Functions
394
Watchdog timer 2 has the following functions.
• Default-start watchdog timer
• Input selectable from main clock, internal oscillation clock, and subclock 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.
INTWDT2 signal)
2. For the non-maskable interrupt servicing due to a non-maskable interrupt request signal (INTWDT2),
When watchdog timer 2 is not used, either stop its operation before reset is executed via this
function, or clear watchdog timer 2 once and stop it within the next interval time.
Also, write to the WDTM2 register for verification purposes only once, even if the default settings
