21.2 Configuration of the JTAG Circuit
The 32172/32173's JTAG circuit consists of the following blocks:
• Instruction register to hold instruction codes which are fetched through the boundary-scan path
• A set of data registers which are accessed through the boundary-scan path
• Test access port (abbreviated TAP) controller to control the JTAG unit's state transitions
• Control logic to select input, output, etc.
A configuration of the JTAG circuit is shown below.
