Method for data transmission

The invention relates to a method for data transmission in which the binary original data is transmitted from a transmitter to a unit of a receiver, preferably to a register, and where the original data is transmitted through one or several data lines. In a method for data transmission in which the binary original data (D, . . . , Dm) is transferred from a transmitter to a unit of a receiver (), selected preferably by means of a binary base address (A, . . . , An), preferably to a register (), where the original data (D, . . . , Dm) and preferably also the base address (A, . . . , An) are transmitted through one or several data lines, the inverted original data (inversion data) (D′, . . . , Dm′) and preferably also the complementary base address (complementary address) (A′, . . . , An′, Ak) are transmitted by the transmitter.The transmitted inversion data (D′, . . . , Dm′) and preferably the transmitted complementary address (A′, . . . , An′, Ak) are inverted in the receiver, the transmitted base address (A, . . . , An) and the transmitted original data (D, . . . , Dm) are compared with the inverted complementary address (A′, . . . , An′) and the inverted inversion data (D′, . . . , Dm′) bit serially (, . . . , n) and (, . . . , m) respectively in each case, or instead of inversion and subsequent comparison an EXOR operation is performed on the base address (A, . . . , An) and (D, . . . , Dm) with complementary address (A′, . . . , An′) and inversion data (D′, . . . , Dm′). The transmitted original data (D, . . . , Dm) is transferred to the unit selected by means of the transmitted base address (A, . . . , An) only if all bit for bit comparisons result in agreement. This ensures error-free data transmission.The method and the circuit arrangement are used in particular for data transmission in vehicle occupant protection system s between a central unit and vehicle occupant protection devices.
