System Design Information
21.9.1
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 65. 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.
•
No pull-up/pull-down is required for TDI, TMS, or TDO.
Figure 64 shows the COP connector physical pinout.
