A.1 Instruction Register
The Instruction Register is a 4-bit register with no parity. When the boundary scan circuitry is reset, the IR is
loaded with the binary value b1111, which is equivalent to the BYPASS Instruction value. The Capture-IR
binary value is b0001, and is shifted out TDO as the IR is loaded.
SAMPLE/PRELOAD) and thirteen private instructions for manufacturing use only. Bit-0 (LSB) is shifted into
the instruction register first.
