Huh!!?? Do you think that the non-volatile MAX II CPLD has a SRAM based "volatile" programming mode?
If you think a flash based (i.e. non-volatile) part has a volatile programming mode, maybe you need to do more research, like reading the MAX II documentation.
thanks for your reply. I have one more doubt, i have read about cfm( configuration flash memory) it is used for isp( in system programming). Does it mean cfm can only be programmed while the board is currently running?
