11 JTAG
The DS3112 device supports the standard instruction codes SAMPLE/PRELOAD, BYPASS, and
EXTEST. Optional public instructions included are HIGHZ, CLAMP, IDCODE (Figure 11-1). The
DS3112 contains the following items that meet the requirements set by the IEEE 1149.1 Standard Test
Access Port and Boundary Scan Architecture:
Test Access Port (TAP)
TAP Controller
Instruction Register
Bypass Register
Boundary Scan Register
Device Identification Register
The Test Access Port has the necessary interface pins, namely JTCLK,
JTRST, JTDI, JTDO, and JTMS.
Details on these pins can be found in Section 2.9. Details on the Boundary Scan Architecture and the Test
Access Port can be found in IEEE 1149.1-1990, IEEE 1149.1a-1993, and IEEE 1149.1b-1994.
