#139949 - I got MOVC! Responding to: ???'s previous message |
Hi again, I tried to use MOVC, now im undertstanding how it works, will fit my need, thanks for all your help...
About clearing Accumulator before using MOVC, I think is because this: MOV A,@A+DPTR... thinking that A is 0 it will read address 0+dptr and put the value on A, lets think it has read 132, now A=132, if use MOV A,@A+DPTR again, it will read address 132+DPTR, if this isnt wanted i will got a buggy program. Its right? But now, I became interested in MCU writing itself code memory, Can AT89S52 do this? Can someone helpme or say where can I get this information? Thanks again. |
