12.1
The DS315x LIUs support the standard instruction codes SAMPLE/PRELOAD, BYPASS, and EXTEST. Optional
public instructions included are HIGHZ, CLAMP, and IDCODE.
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, JTRST, JTDI, JTDO, and JTMS. Details on these pins
can be found in Section 4. Details about the boundary scan architecture and the TAP can be found in IEEE 1149.1-
1990, IEEE 1149.1a-1993, and IEEE 1149.1b-1994.
