User Push Buttons (
8
)
There are five active-high user push buttons available for general purpose usage and are
arranged in a
North-East-South-West-Center
orientation (only the
West
one is cited in
Figure 2-2, page 6
). The user push button connections are summarized in
Table 2-5

User Push Button LEDs (9)
There are 5 green LEDs positioned next to the
North-East-South-West-Center
oriented
push buttons (only the
Center
one is called out in
Figure 2-2, page 6
). The LEDs are active
high and are directly controllable by the FPGA:
