Abstract
A data communication interface for transferring at least one data bit to a host processor. The interface includes a one-wire data line, and a slave processor connected to the data line and including a pull-down circuit for varying voltage on the data line. The slave processor is passive and incapable of sampling data from the data line. The slave processor is programmed to vary voltage on the data line when the data line is energized, to signal at least one data bit.
