For a board with a COP (common on-chip processor) connector that accesses the JTAG interface and needs to reset the JTAG
module, it is not recommended to wire only TRST and PORESET.
To reset the MPC5125 via the COP connector, the HRESET pin of the COP should be connected to the HRESET pin of the
MPC5125. The circuitry shown in Figure 51 allows the COP to assert HRESET or TRST separately, while any other board
sources can drive PORESET.

NOTES:
1 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.
