9.3.6 CLAMP
All digital outputs pins output data from the boundary scan parallel output while connecting the bypass register
between PTDI and PTDO. The outputs do not change during the CLAMP instruction.
9.4
JTAG 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 in the device design. This test register is the identification register, and is
used in conjunction with the IDCODE instruction and the Test-Logic-Reset state of the TAP controller.
9.4.1 Bypass Register
This is a single 1-bit shift register used in conjunction with the BYPASS, CLAMP, and HIGHZ instructions, which
provides a short path between PTDI and PTDO.
9.4.2 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.
9.4.3 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 361 bits in length.
