ANSWER HAS BEEN PROVIDED, I'll like a detailed walkthrough on how to obtain the answer, and any additional information needed to solve this problem.

LC-3, this question is based on the book:

Introduction to Computing Systems: From Bits and Gates to C and Beyond (2nd Edition)

Problem 7 (4 points) We are about to execute the following program: Address ISA Instruction x3000 1110 0000 0000 1110 ; LEA RO, X00E x3001 0010 0010 0000 1110 ; LDR1, X00E x3002 0110 0100 1100 1110 ; LDR R2, R3, X0E x3003 1111 0000 0010 0101 ; HALT The state of the machine before the program starts is given below: Registers RO and R1 contain x200E Memory location X200E contains x3258 Memory location x300E contains x92FE Memory location x3010 contains x2257 Registers R2 and R3 contain x3001 Memory location x2257 contains x0000 Memory location x300F contains x3010 Memory location x3258 contains x0001 What will be the final contents of registers RO-R3 when we reach the HALT instruction? Write your answers in hexadecimal format. Register RO Ri Initial contents X200E X200E x3001 x3001 Final contents x300F x2257 x3010 x3001 R2 R3 Problem 7 (4 points) We are about to execute the following program: Address ISA Instruction x3000 1110 0000 0000 1110 ; LEA RO, X00E x3001 0010 0010 0000 1110 ; LDR1, X00E x3002 0110 0100 1100 1110 ; LDR R2, R3, X0E x3003 1111 0000 0010 0101 ; HALT The state of the machine before the program starts is given below: Registers RO and R1 contain x200E Memory location X200E contains x3258 Memory location x300E contains x92FE Memory location x3010 contains x2257 Registers R2 and R3 contain x3001 Memory location x2257 contains x0000 Memory location x300F contains x3010 Memory location x3258 contains x0001 What will be the final contents of registers RO-R3 when we reach the HALT instruction?
