MPC5200B Data Sheet, Rev. 4
Freescale Semiconductor 67
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.

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.
