You designed your ALU instruction set to include the instruction SUB R1, X, which subtracts the integer stored at address X in main memory from the value in register R1, and places the difference back in R1. The integer values are stored in twos complement representation. Your ALU has addition and complement circuits, but not a subtraction circuit. Sequence the following micro-operations in the correct order to implement this instruction. a. MBR - Increment(MBR)
.b MAR - (IR(address))
c. MBR - Complement(MBR)
d. MBR - Memory
e. R1 - (R1) + (MBR) >
