The T89C51CC01 has an ISP bootloader that can be started from
software. However, it appears that the WDT resets the processor after
the bootloader starts running, causing the processor to start running
the old application. Is there any way around this</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Watchdog resets processor after bootloader started.</title><link>https://community.arm.com/thread/51198?ContentTypeID=1</link><pubDate>Tue, 09 Oct 2007 19:35:28 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:3e402935-4c02-4b59-a01a-85bc054e65f4</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
do a watchog disable (or do not start it). A good WD can not be
disabled when started I do not know the TI chips, thus the duality in
the answer.&lt;/p&gt;

&lt;p&gt;
However, as I believe that TI (as opposed to some others) think
before they make a chip, I guess the WD can not be disabled, in such
a case it would not be an &amp;#39;undue burden&amp;#39; to request bootload command
to be entered, say, within 10 seconds after reset and enable the WD
after such time.&lt;/p&gt;
