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-kΩ 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
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.
