Reset priority module: if S is 0 and R1 is 0, and this is the first execution of the program, what is the output? If this output is the input for a certain module, during the first run, should this input value be 0 or 1? 3. What is the output of the reset priority module OUT?

The first one has a self-holding function, right? For the second one, it depends on whether you use an SR or RS flip-flop; if both outputs are 0 on the first operation, then they will naturally remain 0
