Abstract
A method of using a capacitively coupled interface to increase the integrity of digital signals being transmitted across the interface includes transmitting signals between a first electronic circuit and a second electronic circuit using a capacitively coupled interface, and protecting the integrity of the signals by using a protocol. The protocol preferably includes: Transmitting a signal from the first electronic circuit to the second electronic circuit on the capacitively coupled interface. After the second electronic circuit receives the signal from the first electronic circuit, transmitting a unique synchronization sequence from the second electronic circuit to the first electronic circuit on the capacitively coupled interface. Constructing a status signal that contains information concerning a status of the first electronic circuit. After the first electronic circuit receives the unique synchronization sequence, 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. Determining if the received status signal corresponds to a predetermined status signal, and if the …
