Patent ID: 7430259

Claim:
A method for transmitting data over a two wire serial interface, comprising the steps of: generating a preamble at a master device over a data line and a clock line of the two wire serial interface, the step of generating the preamble further comprising the steps of: transmitting a clock signal on the data line of the two wire serial interface, to a slave device; transmitting a data signal at a logical level on the clock line of the two wire serial interface to the slave device; maintaining the data signal at the logical level for a first number of pulses of the clock signal on the data line; transmitting a data block consisting of address bits via the data signal and data bits on the data line of the two wire serial interface after generation of the preamble; and switching the clock signal from the data line to the clock line to transmit the clock signal on the clock line of the two wire serial interface after the generation of the preamble to the slave device.
