MOV R1, #22H ; set R1 to point at DATA address 22HNow I'm truly a noob here, but doesn't this actually mean: set R1 to the value 22H (0x22H)? You are right - looking at this instruction in isolation, that is precisely what it's doing! Similarly, MOV A, @R1 ; read the value at DATA
; address 22Htaken in isolation is incorrect - it should say, "read the value at the DATA address given by R1"
It would probably have been more helpful if the author had commented the two lines together, rather than individually - as they only have the meaning given in his comments when they are taken together! |
