• Manufacturer Part Number: mpc5200cvr400br2
• Description: Mpc5200b 32-bit Embedded Processor
• Manufacturer: Freescale Semiconductor, Inc

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.
To reset the MPC5200B via the COP connector, the HRESET pin of the COP should be connected to the
HRESET pin of the MPC5200B. The circuitry shown in
JTAG_TRST separately, while any other board sources can drive PORRESET.

With respect to the emulator tool’s perspective:
Input is really an output from the embedded e300 core.
Output is really an input to the core.
From the board under test, power sense for chip power.
HALTED is not available from e300 core.
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).
