3. SETTING UP THE RAS FEATURE
NOTE
When you change the setting to "Retriggered by application program," the
watchdog timer is stopped once. While the watchdog timer is stopped, it will
time out. When a user application retriggers the watchdog timer by using the
WdtControl function of the RAS library, the watchdog timer resumes a
countdown. The state of the watchdog timer (whether it is counting down or
stopped) can be checked using the WdtControl function.
● Automatic retrigger:
If you select this item, the watchdog timer is automatically retriggered by the
automatic retriggering feature for the watchdog timer. In addition, you cannot use
the watchdog timer by calling the WdtControl function of the RAS library.
If this item is selected, you can configure the retrigger interval of the automatic
retriggering feature and the timeout of the watchdog timer.
• Timeout
Sets the timeout of the watchdog timer by using single-byte numeric characters.
Type an integer value between 5 and 60 (in seconds). The default factory-
shipped setting is 60 (seconds).
• Retrigger interval
Sets the retrigger interval of the automatic retriggering feature for the watchdog
timer by using single-byte numeric characters. Type an integer value between 1
and (timeout - 4) (in seconds). The default factory-shipped setting is 20
(seconds).
You can set a timeout and retrigger interval only if you select "Automatic
retrigger." If "Automatic retrigger" is not selected, you cannot enter those
values.
