Max II CPLD DEV_OE and DEV_CLRn

I'm using MAX-II(EPM1270) CPLD and Here is my question: 

 

How these CPLD DEV_OE and DEV_CLRn pins are asserted and deasserted ?? 

I red in MAX-II Data sheet that an option has to be set before compilation in the Quartus II software in order to controls these pins, 

If I want to use these pins what I have to do and if not what to do?  

 

 

Please suggest. 

 

Thanks in advance

The settings can be set in Assignments/Device/Device and Pin Options. It can be found intuitively without reading the Quartus Handbook, I think. (Although the Handbook is always an option).

The solution is to load a design that contains the serial flash loader. You can either include a SFL instance with your design or load the default SFL design for your device, that can be found in the \quartus\common\devinfo\programmer folder.
