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.
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.

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.
