Thus, if you only enable RR0 (by writing 1 to RREN), you only need to write the magic word to RR0 in order to reload the WDT.&lt;/p&gt;
&lt;p&gt;Most application will only need to use one reload request registers. However, more than one may be useful in some cases, for example if you are using a RTOS with several tasks. In that case you may want every task to request a reload of the watchdog, and trigger a system reset if any of the tasks fail to do so.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
