How can it be possible that some noise or interference make it consume more current?</P></BODY></HTML> Tue, 28 Jan 2014 14:25:57 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/Weird-Problem-with-current-consumption-with-PA4-in-STOP3-Mode/m-p/262505#M20032 carloscuev 2014-01-28T14:25:57Z Re: Weird Problem with current consumption with PA4 in STOP3 Mode https://community.nxp.com/t5/8-bit-Microcontrollers/Weird-Problem-with-current-consumption-with-PA4-in-STOP3-Mode/m-p/262506#M20033 <HTML><HEAD></HEAD><BODY><P>Hi Carlos.</P><P></P><P>I would estimate this is result of floating input(s).
