D17 HSMC Port B Present Illuminates when the HSMC port B has a board or cable plugged-in such that pin 160 becomes grounded. Driven by the add-in card D16 HSMC Port A Present Illuminates when the HSMC port A has a board or cable plugged-in such that pin 160 becomes grounded. Driven by the add-in card RXD1 UART_RXD/GPIO Illuminates when RS232 receives data or GPIO Expansion 0 Expansion 0 IO[7] IO[7] is transmits or receives. TXD1 UART_TXD/GPIO Illuminates when RS232 transmit data or GPIO Expansion 1 Expansion 1 IO[9] IO[9] is transmits or receives. USB Illuminates when USB Jack-Mini-USB port has a device. Jack-Mini-USB-AB Port USB_TYPE_A port Illuminates when the USB_TYPE_A port has a device. D15 D14 (Top USB) USB_TYPE_A port Illuminates when the USB_TYPE_A port has a device. (Bottom USB) D13 2.4 General User Input/Output Push-buttons The DE4 board includes six push-buttons that allow you to interact with the Stratix IV GX device. Each push-button provides a high logic level or a low logic level when it is not pressed or pressed, respectively. Table 2–4 lists the board references, signal names and their corresponding Stratix IV GX device pin numbers.
