Functional Description

Miscellaneous I/O
An 8-position DIP switch, 4 user Pushbuttons, and 8 user LEDs are provided on the
Spartan-3A DSP Starter Platform. The connection of these devices to the FPGA is detailed
in
the “OFF” position. Turning the switch “ON” causes the corresponding FPGA pin to be
pulled to 2.5V or 3.3V, depending on the setting of the Bank 0 I/O voltage (VCCO_0). Like
the DIP switch, the four user pushbuttons are also pulled low and depressing any button
will cause the corresponding FPGA pin to be driven to the value of VCCO_0. Driving a
“High” to the LEDs will cause them to light.
