1. A system to communicate between a device and a controller, the system comprising:
- a data line to communicate a data signal of a frequency from said device to said controller;
a clock line to communicate a clock signal of a frequency from said device to said controller; and
a guard line to communicate a guard signal from said device to said controller;
wherein the data signal comprises at least device information to be utilized by the controller;
the clock signal provides a timing reference, for transmission by the device and receipt by the controller, of the data signal;
said timing reference is verified through analysis of the guard signal in relation to the clock signal; and
data signal synchronization occurs through recognition of a bit pattern in the data signal.
