Electronic interface for a bidirectional one-wire communication line with data output of feedback bits only on demand

An electronic interface (1 . . . 1′″, 1a, 1b) for a bidirectional one-wire communication line (2), comprising

• a sender unit (3, 3′) with a line output (LNOUT, LNOUT′), which is designed to be connected to the one-wire communication line (2),
• a receiver unit (4, 4′) with a line input (LNIN, LNIN′), which is designed to be connected to the one-wire communication line (2),
• a data input (DIN . . . DIN′″) for a data signal having sending data bits, which are to be sent over the one-wire communication line (2) via the sender unit (3, 3′), and
• a data output (DOUT . . . DOUT′″) for a data signal having received data bits, which are received over the one-wire communication line (2) via the receiver unit (4, 4′),
• wherein the electronic interface (1 . . . 1′″, 1a, 1b) is designed to forward a feedback bit, which is sent by the sender unit (3, 3′) and fed back to and received by the receiver unit (4, 4′), to the data output (DOUT . . . DOUT′″), and
• wherein the electronic interface (1 . . . 1′″, 1a, 1b) is designed to forward a feedback bit to the data output (DOUT . . . DOUT′″) only on demand.
