Abstract:
A method of using a capacitively coupled interface to increase the integrity of digital signals transmitted across the interface, which comprises:transmitting a signal from a first electronic circuit to a second electronic circuit on the capacitively coupled interface; after the second electronic circuit receives the signal from the first electronic circuit, the second electronic circuit starting a clock signal and transmitting a unique synchronization sequence of data and control bits from the second electronic circuit to the first electronic circuit on the capacitively coupled interface; after the first electronic circuit receives the unique synchronization sequence, the first electronic circuit recognizing the unique synchronization sequence and constructing a status signal that contains information concerning a status of the first electronic circuit; transmitting the status signal and a data signal from the first electronic circuit for reception by the second electronic circuit on the capacitively coupled interface; the second electronic circuit determining if the received status signal corresponds to a predetermined status signal; and if the received status signal corresponds to the predetermined status signal, determining that the received data signal is valid.
