Question
I'm writing to memory space a few address and I need to optimize the code. There is a better way to do the following?
SETB 00h
SETB 01h
SETB 02h
SETB 03h
SETB 04h
SETB 05h
SETB 06h
SETB 07h
Solution
I think what you want to do is:
MOV 20h,#0FFh
this should be equivalent to setting each byte
OTHER TIPS
I see techspecs and indirect adress is better for change
MOV @R0,#0FFh
