Note TRST is an optional pin in the JTAG (IEEE 1149.1) specification,
and is not used by XC9500 CPLDs. If any of your non-Xilinx parts
have a TRST pin, the pin should be connected to VCC
Configuring FPGAs With the Parallel Cable III
This section details the connections needed to configure FPGAs with
the Parallel Cable III.
The following figures show which pins to connect, depending on
your chosen FPGA device. For descriptions of each pin, see Table 3-
6and Table 3-7 of the “FPGA Design Demonstration Board” chapter.
Note If you are using the Xilinx FPGA Design Demonstration Board,
see the “Mode Switch Settings” section of the “FPGA Design Demon-
stration Board” chapter for specific configuration information.
