摘要：A master-slave device communication circuit includes a master device, a bus, anda slave device having a bus switch connected to the master device via the bus, and a statusdetecting circuit. The status detecting circuit includes a power input terminal and adetecting signal output terminal. A power terminal of the master device is connected to
the power input terminal of the status detecting circuit. The detecting signal outputterminal is connected to the bus switch and a trigger pin of the master device. When themaster device supplies power to the slave device via the power terminal thereof, thedetecting signal output terminal transmits a control signal to control the bus switch toturn on the bus and trigger the master device to communicate with the slave device aftera delay time.
