Hi James,

If the words "pointed to" are pretty confusing to you let's try redundant definition.

As you probably know in 8052 the internal memory is splitted in two parts, one lower (range 00H to 7FH) the second higher (range 80H to FFH). When you try to access the higher one you must use the indirrect addressing. That's the sign @ for. If you load R0 with 92H in order to access the contents of this memory belonging to higher memory space, when you do MOV @R0, #62H, that it's the only way through which you can load 62H to internal memory 92H.
The instruction MOV R0, #62H it's pretty obvious.

Regards,
Silviu
