12 JTAG INFORMATION
The device supports the standard instruction codes SAMPLE:PRELOAD, BYPASS, and EXTEST. Optional public
instructions included are HIGHZ, CLAMP, and IDCODE. See Table 12-1. The DS33Z11 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
The Test Access Port has the necessary interface pins:
JTRST, JTCLK, JTMS, JTDI, and JTDO. See the pin
descriptions for details. Refer to IEEE 1149.1-1990, IEEE 1149.1a-1993, and IEEE 1149.1b-1994 for details
about the Boundary Scan Architecture and the Test Access Port.
