15. A current control circuit comprising:
a variable voltage source electrically coupled with a current source and a current sink, whereby the current control circuit is configured to be operable for modulating a supply current from a first device to a second device into different current values for reporting different information from the second device to the first device, wherein the current control circuit is configured to modulate the supply current from the first device to the second device independent from a supply voltage from the first device to the second device.
