Sample Exam Question:
When a JMP execution is executed, the signal GatePC will be enabled (i.e. JMP causes a new value to be loaded into the PC, which is then made available to MAR via the system bus). Looking at the diagram of the LC-3 data path, identify which inputs from the muxes controlled by ADDR2MUX and ADDR1MUX will be fed into the adder that calculates the new PC value, during the execution of a JMP instruction.
