App Note for ETM/IO line sharing

Started by jpsg123 May 21, 2004
Does anybody know of an App Note how to use properly ETM/IO shared ports? Like if I am
going to use P0.22 to P0.31 in my project, how do I handle conflicts when in debug mode
since these line will be configure in a way that is not what it is supposed to be when
running? Do I need series resistors? What value? Do I need to use a transceiver for
isolation? etc. Thanks.
