It is based on a novel self-test technique also applicable to other controller designs. This technique uses a signature register as state register, such that no reconfiguration of that register is necessary during self-test. This way the test of the test access port can be efficiently incorporated into the system self-test. No additional I/O pins beyond those of the boundary scan standard are necessary, neither does the test program have to be changed to incorporate the test of the controller. The solution only requires moderate hardware overheads, nevertheless it guarantees a high fault coverage.
