User LEDs (Active-High)
Callout 23, Figure 1-2.
DS13 through DS20 are eight active-High LEDs that are connected to user I/O pins on the
FPGA as shown in Table 1-10 These LEDs can be used to indicate status or any other
purpose determined by the user.
User DIP Switches (Active-High) and I/O Header
Callout 25, Figure 1-2.
The DIP switch SW2 provides a set of eight active-High switches that are connected to user
I/O pins on the FPGA as shown in Table 1-11. These pins can be used to set control pins or
any other purpose determined by the user. Six of the eight I/Os also map to 2 x 6 test
header J125 providing external access for these pins (callout 26, Figure 1-2.).
