bances and remedying them to return the CPU to normal operation.
timer pin (WDTOUT) by outputting "Low".
The watchdog timer (WDT) is for detecting malfunctions (runaways) of the CPU caused by noises or other distur-
If the watchdog timer detects a runaway, it generates a INTWDT interrupt or reset.
Also, the watchdog timer notifies of the detecting malfunction to the external peripheral devices from the watchdog
Figure 15-1shows the block diagram of the watchdog timer.
Note:INTWDT interrupt is a factor of the non-maskable interrupts (NMI).
Note:This product does not have the watchdog timer out pin (WDTOUT).
