SYSTEM AND METHOD FOR OPERATING A ONE-WIRE PROTOCOL SLAVE IN A TWO-WIRE PROTOCOL BUS ENVIRONMENT

摘要

A method for transmitting data on a data line of a two-wire bus wherein the bus includes a data line and a clock line includes the step of pulling the data line of the two-wire bus low to define a start condition. Next, a first group of fixed data bits enabling a slave device to determine a clock signal for an address portion of a transmission of data are transmitted between a master device and the slave device. An address of the slave device is transmitted from the master device in a second group of data bits. A third group of fixed data bits enabling the slave device to determine the clock signal for a data portion of the transmission of data between the master device and the slave device are transmitted from the master device to the slave device.
