SYS
Fig. 11-1 shows the block diagram of the watchdog timer
The watchdog timer (WDT) is for detecting malfunctions (runaways) of the CPU caused by noises or
other disturbances and remedying them to return the CPU to normal operation. If the timer detects a
runaway, it generates a non-maskable interrupt or an internal reset to notify the CPU. The watchdog
timer starts immediately after reset release.
