Abstract
A digital information transfer apparatus includes N shift registers (1 through N) for storing digital information supplied to and from N respective function modules, and a common bus connected to the shift registers for parallel transfer of digital information. The shift registers are serially connected by a scan path to form a large scale shift register. An error detector in the transferring control circuit detects a failure on the common bus, and supplies a serial output signal of the Nth shift register to the 1st shift register. The processing circuit of the 1st function module rotates the contents of the 1st to Nth shift registers, through the scan path.
