Classification: G06F

Abstract:
A start-stop detection circuit comprising:a first start detecting circuit connected to a clock line to receive a clock signal, and a data line to receive a data signal, the detecting circuit being connected to a first reset line to receive a first reset signal and to a first-step line to output a first-step signal; a second start detecting circuit connected to the clock line to receive the clock signal, the second start detecting circuit being connected to the first-step line to receive the first-step signal, a second reset line to receive a second reset signal, and a start line to output a start signal; a reset circuit connected to the clock line to receive the clock signal, and a master reset line to receive a master reset signal, the reset circuit being connected to the start line to receive the start signal, the first reset line to output the first reset signal, and the second reset line to output the second reset signal; and a stop detection circuit connected to the clock line to receive the clock signal, the data line to receive the data signal, and the reset line to receive the master reset signal, the stop detection circuit being connected to the start line to receive the start signal.
