TAP
Figure 8–2
The TAP controller controls the IEEE Std. 1149.1 boundary-scan testing, as described
in
operate the TAP controller and the TDI and TDO pins provide the serial path for the
data registers. The TDI pin also provides data to the instruction register, which then
generates the control logic for the data registers.
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 3-bit
peripheral elements that are associated with the I/O pins of the MAX V devices. You
can use the boundary-scan register to test the external pin connections or to capture
internal data.
