Key Components and Features
Using one or two external multimeters, measure the corresponding difference in current
Caution! Do not set the SUSPEND switch to “SUSPEND” while programming the parallel NOR
Flash PROM using configuration bitstream #4, as described in
Table 1-2 .RS-232 Serial Port Control Option
Optionally, control the demonstration design using a serial port connection to a PC or
workstation. On a PC, use the HyperTerminal program to communicate to the FPGA
application, as shown in Figure 1-6 . Using a standard, straight-through 9-pin serial cable,
connect the PC’s 9-pin RS-232 port to the board’s DCE connector (see Figure 7-1, page 63 ).

Figure 1-6:
Use HyperTerminal and a Standard Serial Cable to Connect to Board
When the demonstration design begins operating, it transmits a message using the serial
port.
Press a number key on the PC to load the associated MultiBoot bitstream listed in
