JTAG Test Access Port and BDM Debug Port
The MCF5272 implementation can do the following:
Figure 21-1 shows the MCF5272 implementation of IEEE 1149.1.
21.2 JTAG Test Access Port and BDM Debug Port
The JTAG test interface shares pins with the debug modules (see Table 21-1).

• Perform boundary scan operations to test circuit board electrical continuity
• Sample MCF5272 system pins during operation and transparently shift out the result
• Bypass the MCF5272 for a given circuit board test by effectively reducing the

Precautions to ensure that the IEEE 1149.1 test logic does not
interfere with non-test operation are described in Section 21.7,
“Non-IEEE 1149.1 Operation.”
