METHOD FOR REALIZING A PARALLEL CONNECTION, AND A PARALLEL CONNECTION

摘要

The invention relates to a method for realizing a parallel interface in a device that is connected to a micro-controller, and a parallel interface. The interface comprises several signal interfaces (B0 ... B7) in parallel, and the value of each signal is expressed by a corresponding data bit (D0 ... D7) in a memory location, such as a register. To eliminate malfunctions, the data bits (D0 ... D7) of the signal interfaces are divided between the data register (DATA1 ... DATA8) appearing in different addresses (A+1 ... A+8), and in at least one predetermined control address is provided control data (C0 ... C7; M) indicating in which addresses the data bits (D0 ... D7) appear.
