ALP to Move a block of data within internal RAM


ORG 00H
MOV R0, #50H ; R0 points to source memory location (starting from 50H)
MOV R1, #60H ; R1 points to destination memory location (starting from 60H)
MOV R2, #05H ; Loop counter (5 iterations)

Back: MOV A, @R0 ; Load value from memory address pointed by R0 into A
MOV @R1, A ; Store the value of A into memory address pointed by R1
INC R0 ; Increment R0 to point to the next source address
INC R1 ; Increment R1 to point to the next destination address
DJNZ R2, Back ; Decrement R2 and repeat until R2 becomes zero

UP: SJMP UP ; Infinite loop to halt the program
