System for correcting an illegal addressing signal by changing a current bit from one to zero if a bit immediately left adjacent to the current bit is zero

摘要

An apparatus and a method detect and automatically correct an illegal address in a peripheral connect interface bus addressing scheme. The value of a current bit is read. The value of a bit immediately left adjacent of the current bit is read. A value of 0 is outputted as the current bit in the event the value of the current bit is 1 and the value of the left adjacent bit is 0. In one specific embodiment, the apparatus employs a multiplexer and a single-bit register with a feedback as a one bit detection and correction circuit.
