DIP Switches
The user DIP switch is for reference design functions and general purpose use. This
switch connects to the FPGA device I/O pins.
summarizes the function
and connections of the user DIP switch (SW7).
Flash Memory Device
The board features a Numonyx PC28F512P30BF 512-Mb CFI-compliant NOR-type
flash memory device. This device stores configuration files for the FPGA. Both the
MAX II CPLD (U32) and FPGA (U33) devices can access the flash. The MAX II access
the flash for FPP configuration of the FPGA using the PFL Megafunction. The FPGA
access to the flash’s user space for embedded NIOS applications.
lists the
pin-out information of the flash memory interface to the FPGA. The signal direction is
with respect to the FPGA device.
