The pins from the EPF10K20 device are pre-assigned to switches and LEDs on the board. s s s s s s s s s JTAG chain connection for the ByteBlaster Socket for an EPC1 Configuration EPROM 2 momentary push-button switches 1 octal dipswitch Dual-digit 7-segment display On-board oscillator (25.175 MHz) VGA port Mouse port 3 expansion ports, each with 42 I/O pins and 7 global pins FLEX_PB1 & FLEX_PB2 Push-Buttons FLEX_PB1 and FLEX_PB2 are two push-buttons that provide active-low signals to two general-purpose I/O pins on the EPF10K20 device. FLEX_PB1 is connected to pin 28, and FLEX_PB2 is connected to pin 29. Each push-button is pulled-up through a 10-KΩ resistor. FLEX_SW1 Switches FLEX_SW1 contains eight switches that provide logic-level signals to eight general-purpose I/O pins on the EPF10K20 device. An input pin is set to logic 1 when the switch is open and set to logic 0 when the switch is closed. Table 6 lists the pin assignment for each switch.

Each LED segment on the display can be illuminated by driving the connected EPF10K20 device I/O pin with a logic 0. See Figure 4 on page 9 for the name of each segment. Table 7 lists the pin assignment for each segment. Table 7.
