This is the typical value at VCC = 5V.<br /> <br /> &lt;span style=&quot;font-family: Arial;&quot;&gt;&amp;nbsp;&lt;/span&gt;<br /> <br /> By controlling the Watchdog Timer pre-scaler, the Watchdog reset interval can be adjusted from 16K to 2,048K cycles (nominally 16 - 2048 ms). The BASCOM RESET WATCHDOG - instruction resets the Watchdog Timer.<br /> <br /> &lt;span style=&quot;font-family: Arial;&quot;&gt;&amp;nbsp;&lt;/span&gt;<br /> <br /> Eight different clock cycle periods can be selected to determine the reset period.<br /> <br /> &lt;span style=&quot;font-family: Arial;&quot;&gt;&amp;nbsp;&lt;/span&gt;<br /> <br /> If the reset period expires without another Watchdog reset, the AT90Sxxxx resets and program &amp;nbsp;execution starts at the reset vector address.<br /> <br /> <br /> <br /> {{Languages}}<br /> <br /> [[Category:BASCOM_HARDWARE]]</div>
