ABSTRACT:
An electrical circuit and method to compare contents of counter circuits. The electrical circuit comprises a first counter circuit and a second counter circuit electrically connected to a flip-flop circuit through a logic circuit. The first counter circuit is for receiving a first enable signal INC_A and generating a first output signal SIG_A. The second counter circuit is for receiving a second enable signal INC_B and generating a second output signal SIG_B. The first enable signal INC_A and the second enable signal INC_B are for comparing the first output signal SIG_A to the second output signal SIG_B. The flip-flop circuit is for generating a first status signal defining a first relationship between the first output signal SIG_A and the second output signal SIG_B. The logic circuit is for generating a second status signal defining a second relationship between the first output signal SIG_A and the second output signal SIG_B.
