4. Switch to the Full Chip Simulation for debugging by clicking the pull down arrow and selecting Full Chip Simulation. (This
does not use the hardware for debugging. If you want to actually use the HCS12 hardware, choose P&E Multilink Cyclone
Pro.)
5. Create listing files by opening the Simulator Settings panel by clicking the icon shown above.
a. Click on + next to Target in the Target Settings.
b. Highlight Assembler for HC12 and in that panel click on Options.
(i) Check Generate a listing file.
(ii) Check Object File Format. Choose ELF/DWARF 2.0 Object File Format.
(iii) Click OK.
c. Click OK.
6. Open the Sources folder (click on the + if it is not open).
7. Double click on main.asm and enter the following code after the comment

ldab #$02 ; Initialize a counter with data
; Load and store data in a loop
loop:
ldaa 0,x ; Get the data
staa VarData ; Store it in RAM

staa VarData+1 ; Store it
inx ; Increment the pointer
decb ; Decrement the counter
