The LC-3 does not have an opcode for the logical function OR. That is, there is no instruction in the LC-3 ISA that performs the OR operation. However, we can write a sequence of instructions to implement the OR operation. The four-instruction sequence below performs the OR of the contents of register 1 (R1) and register 2 (R2) and puts the result in register 3 (R3). Fill in the two missing instructions (in binary) so that the four instruction sequence will do the job: (1) 1001 100 001 111111 (2) (3) 0101 110 100 000101 (4) Decoding Machine Code Consider the following LC3 Program written in Machine Code. Convert each instruction from Hexadecimal to Binary, and complete the table for each instruction. Note that the Src/Base/Dest registers are referring to the general purpose registers (ROR7), not special purpose registers (PC/IR/etc).
