Normally this interface is implemented, using a COP (common on-chip processor) connector. The COP allows a remote

computer system (typically, a PC with dedicated hardware and debugging software) to access and control the internal operations

of the MPC5200B.

3.4.2 e300 COP/BDM Interface

There are two possibilities to connect the JTAG interface: using it with a COP connector and without a COP connector.

3.4.2.1 Boards Interfacing the JTAG Port via a COP Connector

The MPC5200B functional pin interface and internal logic provides access to the embedded e300 processor core through the

Freescale (formerly Motorola) standard COP/BDM interface. Table 53 gives the COP/BDM interface signals. The pin order

shown reflects only the COP/BDM connector order.

1 With respect to the emulator tool’s perspective, Input is really an output from the embedded e300 core and

output is really an input to the core.

2 From the board under test, power sense for chip power.

3 HALTED is not available from e300 core.

4 Input to the e300 core to enable/disable soft-stop condition during breakpoints. MPC5200B

internally ties CORE_QACK to GND in its normal/functional mode (always asserted).

For a board with a COP (common on-chip processor) connector, which accesses the JTAG interface and which needs to reset

the JTAG module, simply wiring JTAG_TRST and PORRESET is not recommended.
