cmp.l unknown,d0 = I don’t know what value stored in unknown. Therefore their will be three cases (unknown > d0 or unknown < d0 and unknown = d0)
Unknown > d0 = N flag gets set.
Unknown < d0 = no flags get set
unknown = d0 = Z flag gets set

please can you check this if this is correct
cmpi.w #10,d5
What will the states of the N and Z flags would be if
a. d5 = 12 = No flags gets set.
b. d5 = -10 = Z flag gets set.
c. d5 = 5 = N would be set
i think is zero
Decision Making: In high level languages we use instructions of the form
If A< B then P else Q
Now what actually happens deep down in the machine is a subtraction of the form (A – B) and we look at the sign of the result.
If B is greater than A then the result...
[b]1. Given that the instruction
cmp.l d0,d1
subtracts d0 from d1 without changing either and then sets the flags accordingly.
What will be the state of the N and Z flags if
