TEST CIRCUIT BOARD ADAPTED TO BE USED ON SERIAL ADVANCED TECHNOLOGY ATTACHMENT CONNECTOR

摘要

A test circuit board adapted to be used on SATA connector is provided. Two test circuit boards can be seriously connected with each other through a first JTAG connection interface and a second JTAG connection interface. Therefore, the efficiency of reducing TAPs of TAP controller and providing test signal coverage of all of test signals may be achieved.
