6.2.2 Signaling
In order to increase the resistance to interference, transmitting the signals in an
interpolated form is recommended. Transmitting signals in opposite phases
symmetrically can almost entirely prevent interference. The amplitude of the
differentially transmitted signals equates to 1V
For single-ended signaling, the voltage changes relative to a reference potential.
The amplitude of such a signal amounts to 0.5 V.
This interface works with all standard controllers that support a 1 V
interface.
