Abstract:
A method for data transmission, comprising the steps:a) transmitting a binary base address from a transmitter to a receiver; b) selecting a particular selected receiver unit in the receiver responsive to and dependent on the binary base address; c) preparing a complementary address as a complement of the binary base address, and transmitting the complementary address from the transmitter to the receiver; d) transmitting m binary original data in parallel through m data lines from the transmitter to the receiver; e) inverting the original data to prepare therefrom inversion data, and transmitting the inversion data from the transmitter to the receiver; and f) carrying out one of the following f1) or f2): f1) inverting the inversion data to prepare therefrom inverted inversion data and inverting the complementary address to prepare therefrom an inverted complementary address in the receiver, comparing the original data bit-serially with the inverted inversion data and comparing the binary base address bit-serially with the inverted complementary address, and providing the original data to the particular selected receiver unit in the receiver only if the original data corresponds bit-serially with the inverted inversion data and the binary base address corresponds bit-serially with the inverted complementary address, or f2) performing a bit-serial EXOR operation on the original data and the inversion data, performing a bit-serial EXOR operation on the binary base address and the complementary address, and providing the original data to the particular selected receiver unit in the receiver only if both of the bit-serial EXOR operations result in a logical â€œ1â€  in each case.
