Recall that the op-code and operand are represented in memory by HEX numbers (e.g., LDAA $3000 will show in memory as $B6, $30, and $00). Write a short program to use the commands LDAA and STAA to load and store a value of your choice.

Then show in your screenshots the machine language op-code and operand of these instructions and where in memory this is stored.

Finally, execute and show the relevant registers and memory locations in your screenshots.

Take note of how many cycles where needed to fetch, decode, and execute each instruction (i.e., LDAA will take an "x" amount of cycles and STAA will take an "x" amount of cycles).

Hint: See the register window in the CW simulator and the "HCS12 instruction set reference" on the course website.

Can someone explain how to do this please?
