Memory-to-memory direct-to-direct

This addressing mode is generally used to transfer variables and registers in page zero. The A register is not affected. See the following listing for an example of using the memory-to- memory direct-to-direct addressing mode.

Listing: Memory-to-memory direct-to-direct addressing mode

MyData1:  EQU   $50
MyData2:  EQU   $51

entry:

          MOV   #$10, MyData1

          MOV   MyData1, MyData2

The MOV #$10,MyData1 instruction stores the value $10 in memory location $50`MyData1' using the memory-to-memory Immediate-to-Direct addressing mode. The MOV MyData1,MyData2 instruction moves the content of MyData1 into MyData2 using memory to memory Direct-to-Direct addressing mode. The content of MyData2 (memory location $51) is then $10.
