Abstract: An address polling method and system for communicating unique slave address values to a master device over a shared bus. The method includes receiving a request signal from the master device requesting that a slave address from each slave device coupled to the data line be sent to the master; causing, in a serial manner, the data line to be placed in logic states corresponding to bit values in a first slave address; and upon the data line being placed in a logic state that is different from a corresponding bit value of the first slave address, determining that another slave device is placing its slave address on the data line and temporarily entering an idle state until such other slave device has finished communicating its slave address to the master device.

Abstract: A master/slave data communication system in which a master device communicates with the slave devices by uniquely addressing each of the slave devices. In order to enhance the security of the data communication system, each slave device includes an address generator for generating unique addresses. Periodically, the master device requests that one or more slave device change its address. In response to the request, the addressed slave device increments its address generating algorithm to provide a new slave address. The master device also includes an algorithm that is synchronized with the slave address generating algorithm, whereby when the slave changes its address, it need not transmit the new slave address to the master device over the bus.
