#188430 - memory access Responding to: ???'s previous message |
Beautiful! gotta check this out now. Thanks.
.db is going to place bytes in CODE/ROM, * enable XDATA * use MOVC to read Code/Flash * use MOVX to write to XDATA * Use MOVX to read XDATA. Gotta say, some of the 6440 mem features are a bit confusing sram 0..FF, Extra sram 000..FFF, flash data ram 1000..2FFF xram 3000..FFFF code, data, Cdata, Edata, Xdata.. different memory types-Cseg,Dseg,Eseg,Xseg,Iseg.. Rick ps. yes- love the auto increment and dual dptrs. |
