Table 5. Connections made from the T2080RDB-PC COP connector
Pin no. Signal name Connection
1 TDO Connected directly between the processor and JTAG/COP connector.
2 NC Not connected.
3 TDI Connected directly between the processor and JTAG/COP connector.
4 TRST Routed to the RESET PLD. TRST to the processor is generated from the PLD.
5 NC Not connected.
6 VDD_SENSE Pulled to 3.3 V using a 10 Ohm resistor.
7 TCK Connected directly between the processor and JTAG/COP connector.
