就是在那个选择配置方式的开关SW12旁边有六个开关,左边三个开关好像跟这个configuration images有关。相关的话是The three leftmost switches choose one of eight possible configuration addresses。These three DIP switches provide the System ACE controller and the CPLD the possibility of using up to eight different configuration images as set by these three switches. The Platform Flash memory supports up to four different images。
