#29369 - RE: HOW TO ACCESS 512K OF EXTERNAL MEMORY |
The MX series have an EPTR (24 bit DPTR). I have not used the MX myself, but do believe that the INC DPTR and MOVX @DPTR are true 24 bit addressed instructions. Check with your Philips supplier. In the back of my mind, I seem to recall that Dallas also have an extended addressing '51, check it out.
What tools are you using, if Keil, ask Keil etc. Erik |
