1. The following instructions form a program, i.e. they are executed in sequence. Fill in the blanks in the table to indicate the state of CCR (CCR is initially cleared, i.e. all flags are 0) after execution of each instruction. (13 points) MOVE . L #3, SUB . L #5, ADD . L #1, ADD . L #1, ADD . L #1, %DO %D0 %D0 %DO %D0 Which 2-input logic gate (AND, OR, NAND, NOR, XOR, XNOR) (choose only 1 type but you can use more than 1 gate) would you use to implement the functionality of the Z flag of the CCR in hardware? Show your hardware design assuming you are checking a 4-bit register
