Claim:
1. An inter-integrated circuit (I2C) compatible device comprising: a serial data line (SDA) interface for connection to an SDA line of a bus; a single-line I2C module configured to: transmit a sync word from the SDA interface over the SDA line of the bus, wherein the sync word is a SYNC BYTE+Not Acknowledge (NACK) bit; and following transmission of the sync word, transmit I2C data from the SDA interface over the SDA line of the bus such that digital data is communicated over the bus via a single line, wherein the next byte that is transmitted from the SDA interface over the SDA line of the bus following the sync word is a 7 bit slave address plus a data direction bit formatted according to the I2C specification, wherein the data direction bit indicates either a write operation or a read operation.
