    摘要: A system, method, and apparatus for controlling tri-state drivers are presented herein. During scan testing, a decoder controls the tri-state drivers and prevents more than one tri-state driver from driving a shared resource, regardless of the test patterns shifted into the scan chain. During functional mode, the tri-state drivers are driven by functional enables.
