Detailed Description
Figure 1-9 shows the user test I/O connector J125 (callout 26 , Figure 1-2 ).
User Pushbuttons (Active-High)
Callout 24 , Figure 1-2 .
SW4 and SW5 are active-High user pushbuttons that are connected to user I/O pins on the
FPGA as shown in
Table 1-12 . These switches can be used for any purpose determined by
the user.
