CHAPTER 12 WATCHDOG TIMER

12.2

Watchdog Timer Operation

The watchdog timer function enables detection of program surge.
If the watchdog timer is not accessed within the specified time due to, for example, a
program surge, the watchdog timer resets the system.

■

State Transition Diagram of the Watchdog Timer

The watchdog timer has four states:

Inactive:

The watchdog timer does not operate.

Running:

The watchdog counter is counting up from "0".

Stopped:

The watchdog counter is stopped at count value "0".

Overflow: The watchdog counter asserts a watchdog reset.
