2.3. IEEE Std. 1149.1 Boundary-Scan Register
The boundary-scan register is a large serial shift register that uses the TDI pin as an input and the TDO pin as an output. The boundary-scan register consists of boundary-scan cells for each I/O pin and padding bits. You can use the boundary-scan register to test external pin connections or to capture internal data.
Figure 2. Boundary-Scan RegisterThis figure shows how test data is serially shifted around the periphery of the IEEE Std. 1149.1 device.
