So if my external memory starts at 4000H You mean, "external[1] data memory" , then
MOV DPTR, #4000H MOVX A, @DPTR should put the byte at 4000h into A. correct? Again, you need to be clear that it's "external[1] data memory" Have you checked in the so-called "bible" yet? That really is the best reference source for this kind of question! (It sorted my mis-reading!) [1] Again, remember that so-called "external" memory on modern chips may actually be on the chip! |
