ABSTRACT:
An apparatus and method for accessing hidden data in a boundary scan test interface is disclosed, which defines an invalid state transition loop in a boundary scan test interface and initially monitors an input of state transition diagram of the boundary scan test interface so that an output of a first data is generated when a first predetermined input stream conforming to the invalid state transition loop is detected and next an output of a second data is generated when a second predetermined input stream conforming to the invalid state transition loop is detected, wherein when an input key included in a combination of the first and the second data is matched with a predetermined write key, a specific write data is loaded into a hidden register.
