Boards Without COP Connector
If the JTAG interface is not used, TRST should be tied to PORESET, so that it is asserted when the system reset signal
(PORESET) is asserted. This ensures that the JTAG scan chain is initialized during power on. Figure 62 shows the connection
of the JTAG interface without COP connector.
