#65462 - homework problem- |
Hi Guys, I promise this code is not as horribly written as the last I posted. The problem:add the first 32 code locations,write high sum to XRAM 2000h and low sum to 2001h.
I am new to programming and I assure you I don't want anything more than a little guidance. This is what I have written and if any of you are willing your help is appreciated. .ORG 2010H MOV R6,#00 ;CLEAR HIGH SUM REGISTER MOV R7,#32 ;COUNT=32 CLR A MOV DPTR,#0000H DONE:MOVC A,@A+DPTR MOV R0,#50H ;INIT. MEMORY POINTER (50H) MOV @R0,A ;STORE DATA INC DPTR DJNZ R7,DONE MOV R7,#32 ;COUNT=32 MOV R0,#50H MOV A,@R0 NEXT:INC R0 ADD A,@R0 JNC MORE ;JUMP TO MORE IF DONE INC R6 ;INCREMENT HISUM MORE:DJNZ R7,NEXT ;COUNT-1 MOV DPTR,#2001 MOVX @DPTR,A MOV DPTR,#2000 MOV A,R6 MOVX @DPTR,A LJMP 0000 ;END ;CODE MEMORY ;0000: 02 08 5F 02 20 03 8E 82 8F 83 22 02 20 0B AE 82 ;0010: AF 83 22 02 20 13 74 2D 01 76 00 02 20 1B 11 76 |
