System Design Information
Freescale Semiconductor
76
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 MPC5200 via the COP connector, the HRESET pin of the COP should be connected to the
HRESET pin of the MPC5200. The circuitry shown in Figure 55 allows the COP to assert HRESET or
JTAG_TRST separately, while any other board sources can drive PORRESET.

NOTES:
1
With respect to the emulator tool’s perspective:
Input is really an output from the embedded G2_LE core.
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 G2_LE core.
4
Input to the G2_LE core to enable/disable soft-stop condition during breakpoints. MPC5200
internal ties core_qack_ to GND in its normal/functional mode (always asserted).
