Odd. Looks like Port K could be set to either GPIO or extended bus mode (where PK6:0 are output), according to Chapter 22 in the datasheet, Table 22-1. But input only? Only on PK7, in the extended bus mode. It sounds like something strange might be connected to that pin.<BR /><BR />---Tom</BODY></HTML> Thu, 08 Mar 2007 23:41:36 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/I-O-problem-with-9s12DP512/m-p/125540#M341 J2MEJediMaster 2007-03-08T23:41:36Z Re: I/O problem with 9s12DP512 https://community.nxp.com/t5/S12-MagniV-Microcontrollers/I-O-problem-with-9s12DP512/m-p/125541#M342 <HTML><HEAD></HEAD><BODY>That's right,<BR />I think the same so i've deconnected this pin from the electronics and it's the same problem....i can't use PK4 as an output... the others pin work well. I don't have this problem with the 9s12dp256...i'm transfering an application from one micro to the other...<BR />I'm not working in an special mode, just normal single chip mode....<BR /><BR />Thank's for your help<BR /><BR />Wish</BODY></HTML> Thu, 08 Mar 2007 23:53:25 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/I-O-problem-with-9s12DP512/m-p/125541#M342 wishmerill 2007-03-08T23:53:25Z
