Question
Please I need help to pass this EXAM it due TOMORROW . I post 10 separate quastions for that EXAM.
At the end of an LD instruction midway through the execution of an LC-3 program, the contents of the condition codes are set as follows: N-1, 2-1, P 0. What can you conclude 3) There are three addressing modes available to the assembly language programmer who wishes to load a value from memory into RS. If the load instruction is in a loop and each time through the loop, the next consecutive memory location is loaded into RS, which addressing mode is most a to use? Explain why 4) What is the output of the following program?Explanation / Answer
If you specify pre-indexed addressing (where the base and index are both within square brackets), the write-back is controlled by the presence or absence of the '!'.
Using this, you can automatically move forward or backward in memory.
A string print routine could then become:
instead of:
The use of '!' is invalid for post-indexed addressing (where the index is outside of the square brackets)
