General User Interfaces
1 Pin AE17 is the DEV_CLRn pin; when enabled in the Quartus II
software, it will reset all Arria GX device registers. The
USER_RESET
push button is board reference S4. Pin AE17 can
also be used as a standard input.
User-Defined DIP Switch (S3)
Board reference S3 is an eight-pin DIP switch. The DIP switches in S3 are
user-defined, and are provided for additional FPGA input control. Each
pin can be set to a logic 0 by setting it to the closed position, and each pin
can be set to logic 1 by setting it to the open position.
Table 2–14 lists the DIP switch settings, schematic signal name, and
corresponding Arria GX device’s pin number.
