Totally missed that you were doing MOVC @A+DPTR !!
I was thinking MOVX A, @DPTR Looks like I need some "bible" time, too - and/or some glasses... Andy, that's MOVC A, @A+DPTR Valentin, So if my external memory starts at 4000H, then MOV DPTR, #4000H MOVX A, @DPTR should put the byte at 4000h into A. correct? |
