 I have leak current when GPIO disconnect. When I tested it, the pull-up is a problem. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Test the following current waveforms.

&lt;p&gt;The internal pull-up will&amp;nbsp;continue to&amp;nbsp;drive the output pin even&amp;nbsp;if you disconnect the input buffer. So there seems to be an error in the illustration (figure 21). I will report this internally. Sorry for the confusion.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
