7 JTAG BOUNDARY SCAN ARCHITECTURE AND TEST ACCESS PORT
The DS26303 IEEE 1149.1 design supports the standard instruction codes SAMPLE/PRELOAD, BYPASS, and
EXTEST. Optional public instructions included are HIGHZ, CLAMP, and IDCODE. The DS26303 contains the
following as required by 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
Details on 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. The Test Access Port has the necessary interface pins: JTRSTB, TCLK,
JTMS, JTDI, and JTDO. See the pin descriptions for details. For the latest BSDL file go to
