      Joint Test Access Group (JTAG) Information
      Figure 14: JTAG Block Diagram
      Microprocessors and Application Specific Integrated Circuits (ASICs) pose many design challenges, one
      problem being the accessibility of test points. JTAG formed in response to this challenge, resulting in IEEE
      standard 1149.1, the Standard Test Access Port and Boundary Scan Architecture.
      The JTAG boundary scan test methodology allows complete observation and control of the boundary pins of
      a JTAG-compatible device through JTAG software. A Test Access Port (TAP) controller works in concert with
      the Instruction Register (IR), which allow users to run three required tests along with several user-defined tests.
      JTAG tests allow users to reduce system debug time, reuse test platforms and tools, and reuse subsystem tests
      for fuller verification of higher level system elements.
      The 1149.1 standard requires the following three tests:
      Extest Instruction. The Extest Instruction performs a printed circuit board (PCB) interconnect test. This
      test places a device into an external boundary test mode, selecting the boundary scan register to be
      connected between the TAP Test Data In (TDI) and Test Data Out (TDO) pins. Boundary scan cells are
      preloaded with test patterns (through the Sample/Preload Instruction), and input boundary cells capture the
      input data for analysis.
      Sample/Preload Instruction. The Sample/Preload Instruction allows a device to remain in its functional
      mode, while selecting the boundary scan register to be connected between the TDI and TDO pins. For this
      test, the boundary scan register can be accessed through a data scan operation, allowing users to sample
      the functional data entering and leaving the device.
