DIP Switches for FPGA Image Selection
AXC003 CPU card has SPI flash ROM that contains two FPGA images
– HS36 and HS38x2.
One of these images is selected on reset stage depending on DIP-switch settings. The DIP-
switches are in the SW802 IMAGE SELECT component.
Bits of SW802 define the FPGA image that will be selected:
00
– HS36
01
– HS38x2
