Abstract
A scannable logic unit includes one or more storage registers that maintain copies of data communicated from the scannable unit to registers in a nonscannable unit. When the scannable unit is subjected to a scan test, the registers will contain state information respecting that transfer to the nonscannable unit. When the scannable and nonscannable units are placed in a run condition, the registers supply to the nonscannable unit state information for continuing operation.
