I am currently working with a range of peripherals whos control lines look remarkably like an I2C interface.
The data sheets go into great detail about how the data and clock line are used to communicate with the device and how it has an own 'address' so that you can differentiate it from other devices etc.......
Why not just say that it's an I2C comptable device FFS.
Do they have to pay Philips some extra money for admitting that it's I2C rather than pretending that it is something else?
(and is it really still in patent after 20 years?)
sorry rant over.
