10.1 Functions
422
The watchdog timer has the following functions.
• Reset mode: Reset operation upon overflow of the watchdog timer (generation of WDTRES signal)
• Non-maskable interrupt request mode:
Caution The watchdog timer is stopped after reset is released.
Non-maskable interrupt operation upon overflow of the watchdog timer (generation of INTWDT signal)
It starts operating when “ACH” is written to the WDTE register. Also, write to the WDTM
register for verification purposes only once, even if the default settings (reset mode, interval
time: 2
