Question

Is there a sequence of LC-3 instructions that will cause the condition codes at the end of the sequence to be N 1 Z 1 and P 0 explain?

Answer 1

Yes, there is a sequence of LC-3 instructions that can cause the condition codes to be N=1, Z=1, and P=0.

Step-by-step explanation:

Yes, there is a sequence of LC-3 instructions that can cause the condition codes to be N=1, Z=1, and P=0. One example is the following:

1. AND R0, R0, #0
2. ADD R0, R0, #-1
3. BRp loop
4. HALT

In this sequence, the first two instructions set R0 to a negative value, which sets the negative (N) condition code to 1. Then the BRp instruction branches to the label 'loop' if the positive (P) condition code is 0, which is the case here. Finally, the HALT instruction ends the sequence.
