For PICs with more than one ICSP interface (PGC/PGD pair), you can use any = one=20 for programming without any special setting or configuration (except for th= e=20 switch on your board). For debugging, you must make the correct setting for ICESEL in one of the=20 device configuration words. See Special Features section in the datasheet. And by the way, do not clear the DEBUG bit(s) in the configuration words, t= he=20 debugger tool does that for you automatically. /Ruben > I have the Microstick II and have been using it quite successfully. >=20 > However, there is one thing I can't figure out - the little switch on > the side.
