When chaining the generic 1-bit ALU unit shown together to build an n-bit ALU, which of the following in TRUE? (Select All that Apply) Carryin CiCo O A Cin V 0 + Sum Cout Result B- O8 1 2 C Co Operation 0 0 A+B 0 1 A-B 1 0 B-A 1 1 SLT Less 3 CarryOut Set C.Co The Zero signal is created by NOR-ing the Results for all units together. The Carryin of the least-significant bit (LSB) is set to o for addition, 1 otherwise. The Set output from the least-significant bit (LSB) is connected to the Less input of the most-significant bit (MSB). The CarryOut of the lower bit is connected to the Carryin of the upper bit. The Less input of most-significant bit (MSB) unit is set to 1
