System Design Information
The COP interface has a standard header, shown in Figure 67, for connection to the target system, and is
based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). The
connector typically has pin 14 removed as a connector key.
The COP header adds many benefits such as breakpoints, watchpoints, register and memory
examination/modification, and other standard debugger features. An inexpensive option can be to leave
the COP header unpopulated until needed.
There is no standardized way to number the COP header shown in Figure 67; consequently, many different
pin numbers have been observed from emulator vendors. Some are numbered top-to-bottom then
left-to-right, while others use left-to-right then top-to-bottom, while still others number the pins counter
clockwise from pin 1 (as with an IC). Regardless of the numbering, the signal placement recommended in
Figure 67 is common to all known emulators.
For a multi-processor non-daisy chain configuration, Figure 68, can be duplicated for each processor. The
recommended daisy chain configuration is shown in Figure 69. Please consult with your tool vendor to
determine which configuration is supported by their emulator.
20.9.1 Termination of Unused Signals
If the JTAG interface and COP header will not be used, Freescale recommends the following connections:
TRST should be tied to HRESET through a 0 k
Ω isolation resistor so that it is asserted when the
system reset signal (HRESET) is asserted, ensuring that the JTAG scan chain is initialized during
the power-on reset flow. Freescale recommends that the COP header be designed into the system
as shown in Figure 68. If this is not possible, the isolation resistor will allow future access to TRST
in case a JTAG interface may need to be wired onto the system in future debug situations.
Tie TCK to OVDD through a 10 kΩ resistor. This will prevent TCK from changing state and
reading incorrect data into the device.
No connection is required for TDI, TMS, or TDO.
