The DS325xx LIUs support the standard instruction codes SAMPLE/PRELOAD, BYPASS, and EXTEST. Optional
public instructions included are HIGHZ, CLAMP, and IDCODE. The devices contain the following items, which
meet the requirements set by the IEEE 1149.1 Standard Test Access Port and Boundary Scan Architecture:
The TAP has the necessary interface pins, namely JTCLK,
can be found in
1990, IEEE 1149.1a-1993, and IEEE 1149.1b-1994.
IEEE 1149.1 requires a minimum of two test registers—the bypass register and the boundary scan register. The
bypass register is a 1-bit shift register used with the BYPASS, CLAMP, and HIGHZ instructions to provide a short
path between JTDI and JTDO. The boundary scan register contains a shift register path and a latched parallel

parallel output.
