The chip is in an undefined state since the various clocks, regulatores and peripherals have not received a reset signal internally.</p> [quote user=""]And what happens &quot;<span style="color:rgba(255, 0, 0, 1);">after</span>&quot; such a thing occurs, and other resets are done with a correct rise time.[/quote] <p>Only a new power on reset (within specified rise time) will guarantee that the chip become functional again.</p> <p>Kenneth</p> <p></p><div style="clear:both;"></div>
