Abstract
In a data transmission method and circuit for communication between a programming apparatus and a user apparatus to be programmed, such as a hearing aid, data as well as clock pulses are transmitted by the programming apparatus to the user apparatus for the individual adjustment of application-specific data of the user apparatus. The data and clock pulses are transmitted in half-duplex operation using a single signal line. Differently fashioned clock pulses of an outgoing signal with digital information are supplied to the signal line, and the digital information is recovered at the user apparatus by means of clock pulse variation, and the recovered information is subsequently processed with the transmitted clock pulse.
