Abstract
In order to reduce the number of lines of a standard bus while, at the same time, preserving the compatibility of the communications protocol, the system uses a modified bus. The modification consists in eliminating two power supply lines and in creating a line assigned to a functional signal that is complementary to one of the functional signals of the system. The supply potentials are regenerated from the functional signal and the complementary signal. The disclosed system can be applied notably to systems using I2C buses such as systems using chip-card readers.
