JTAG INFORMATION
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:
Test Access Port (TAP)
TAP Controller
Instruction Register
Bypass Register
Boundary Scan Register
Device Identification Register
The TAP has the necessary interface pins, namely JTCLK, JTRST, JTDI, JTDO, and JTMS. Details on these pins
can be found in Table 7-9. 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.
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
output
for
control
cells
and
digital
I/O
cells.

been included in the device design. The identification register contains a 32-bit shift register and a 32-bit latched
parallel output. Table 10-1 shows the identification register contents for the DS32506, DS32508, and DS32512
devices.
