P-Bus and I-Bus
A 'bus' is a group of leads through which information is sent in digital and serial forms. Digital means that the voltage difference between the leads has
only two values, approximately 0 and 5 V. The information is coded so that different combinations of impulses with values 0 and 5 have different
meanings.
