19.1.1. EXTEST Instruction
The EXTEST instruction is accessed via the IR. The Boundary DR provides control and observability of all the
device pins as well as the SFR bus and Weak Pullup feature. All inputs to on-chip logic are set to one.
19.1.2. SAMPLE Instruction
The SAMPLE instruction is accessed via the IR. The Boundary DR provides observability and presetting of the
scan-path latches.
19.1.3. BYPASS Instruction
The BYPASS instruction is accessed via the IR. It provides access to the standard 1-bit JTAG Bypass data register.
19.1.4. IDCODE Instruction
The IDCODE instruction is accessed via the IR. It provides access to the 32-bit Device ID register.
