Notes:
1. Utilizing dual and quad SPI modes.
2. Parallel configuration mode bus is auto-detected by the configuration logic.
3. Spartan-6 devices also have a dedicated four-wire JTAG (IEEE Std 1149.1) port that is always available to the FPGA regardless of the
mode pin settings.
4. Default setting due to internal pull-up termination on Mode pins.
With the mode switch SW1 set to 01, the SP605 will attempt to boot or load a bitstream
from either the SPI X4 Flash device U32 or a user supplied SPI Flash memory mezzanine
card installed on the SPI programming header J17, depending on the SPI select jumper J46
configuration, as shown in
boot or load a bitstream from Linear Flash device U25 (BPI).
With the mode switch SW1 set to 10, if a CompactFlash (CF) card is installed in the CF
socket U37, System ACE CF will attempt to load a bitstream from the CF card image
address pointed to by the image select switch S1. With no CF card present, the SP605 can be
configured via the onboard JTAG controller and USB download cable as described in
