Hi,
I'm using this micro XC864 for first time, I've bought the starter kit ( kit_xc864_ek_v1 ) but now I even don't know if it can be used to program in situ my micro put on my final application or is just an evaluation board without external programing possibilities.
In case of being possible the external programing, which ports would be necessary to bring to the micro wewould like to program?
thank you
" the R232 of my PC it's at logical levels of +/-9V"
That's right - RS232 uses "bipolar" voltage levels.
"XC864 works on 3,3V what should I put between that two points?"
You need an RS232 Transceiver - like the MAX232 or one of its very many successors.
Alternatively, use one of these:

I just got one final question, is the next schematic right? :
picasaweb.google.es/.../xztbGJsRk1CIwnguyZAUJw
I mean, I can program the xc864 using the UART port P0.2 and P0.1? , or I need to use the ports P1.0-P1.1 as in the demo board?
