2.8 PS2 Keyboard & Mouse Ports

The Spartan-3 Dev Board includes two standard 6-pin Mini-Din (PS2)
connectors labeled JS1 and JS2. This two-wire interface will provide connection to PS2 Mice or Keyboards. Since this is a two wire
interface, only pins Data (pin-1) and Clk (pin-5) are connected to the FPGA. The following table provides the pinout for JS1 & JS2.

* Note: PS2 signals are connected to the FPGA by way of a bus switch (JP20 ON). This allows the re-use of header signals. If you
wish to use the 50-pin header J17, you may disable the bus switches by removing JP20. Removing JP20 will disconnect the PS2
connectors from the FPGA.

2.9 Dip & Push-Button Switches

An eight-position dipswitch (SPST) has been installed on the board and attached to the FPGA. These switches provide digital inputs to
user logic as needed. The signals are pulled low (0) by 10K ohm resistors when the switch is open and tied to 2.5V (1) when the switch
is closed.

Table 15 - Dipswitch FPGA Pin-out

Two momentary closure push buttons have been installed on the board and attached to the FPGA. These buttons can be programmed
by the user and are ideal for logic reset and similar functions. Pull down resistors hold the signals low (0) until the switch closure pulls it
high (1).
