IDCODE
When the IDCODE instruction is latched into the parallel instruction register, the identification test
register is selected. The device identification code will be loaded into the identification register on the
rising edge of JTCLK following entry into the capture-DR state. Shift-DR can be used to shift the
identification code out serially via JTDO. During Test-Logic-Reset, the identification code is forced into
the instruction register’s parallel output. The ID code will always have a 1 in the LSB position. The next
11 bits identify the manufacturer’s JEDEC number and number of continuation bytes followed by 16 bits
for the device and 4 bits for the version Table 17-2. Table 17-3 lists the device ID codes.

17.2 Test Registers
IEEE 1149.1 requires a minimum of two test registers: the bypass register and the boundary scan register.
An optional test register has been included with the DS26504 design. This test register is the
identification register and is used with the IDCODE instruction and the Test-Logic-Reset state of the TAP
controller.
17.3 Boundary Scan Register
This register contains both a shift register path and a latched parallel output for all control cells and
digital I/O cells and is n bits in length. See Table 17-4 for the cell bit locations and definitions.
17.4 Bypass Register
This is a single 1-bit shift register used with the BYPASS, CLAMP, and HIGHZ instructions that
provides a short path between JTDI and JTDO.
17.5 Identification Register
The identification register contains a 32-bit shift register and a 32-bit latched parallel output. This register
is selected during the IDCODE instruction and when the TAP controller is in the Test-Logic-Reset state.
