5.4.2.2 Boards without COP connector
If the JTAG interface is not used, JTAG_TRST should be tied to PORRESET, so that it is asserted when
the system reset signal (PORRESET
) is asserted. This ensures that the JTAG scan chain is initialized
during power on. Figure 56 shows the connection of the JTAG interface without COP connector.
