Please show a step by step solution using correct LC-notation and explain. Thanks!

1.) Write a sequence of LC-3 instructions (in bits) to set R3 equal to R4 OR R5. Assume that values have already been placed into R4 and R5 for you. You may not change the values of any other registers (only R3, R4, and R5). Include RTL or assembly comments explaining the action of each binary instruction. Hints: You MAY change R4 and R5. You should only need four instructions.

The following LC-3 instructions execute starting from the point shown by the comment.

1011 1110 1110 1111 ; this is the content of address D=xDEAD

; start LC-3 execution here

0010 100 111111110

0101 101 100 1 10000

1011 101 111111100

; end LC-3 execution here

After the code reaches the end of the code (the last comment), what bits are held in R4? And in R5? And in R7? And in memory address D? If you cannot know the bits held, explain why.

6. The following LC-3 instructions execute starting from the point shown by the comment. 1011 1110 1110 1111 ; this is the content of address DeXDEAD ; start LC-3 execution here 01e1 101 100 1 1000 ; end LC-3 execution here After the code reaches the end of the code (the last comment), what bits are held in R4? And in R5? And in R7? And in memory address D? If you cannot know the bits held, explain why
