AN-1054 GreenPAK Macro Circuit RS flip flop with Reset priority

RS flip flop or SR flip flop — is a circuit that keeps its previous state when both inputs are LOW, and changes its state when one of the inputs (Set or Reset) is HIGH. If Set input goes HIGH, Output will go HIGH, and if Reset goes HIGH the Output will go LOW. In a classic cross coupled logic gate circuit, the output is undetermined when both inputs are HIGH. The design presented in this application note assigns priority to RS to solve that limitation.
