"Smaller Cyclone III devices or package options (E144, M164, Q240, F256, and U256 

packages) do not have the MSEL[3] pin. The AS Fast POR configuration scheme at 3.0- 

or 2.5-V configuration voltage standard and the AP configuration scheme are not 

supported in Cyclone III devices without the MSEL[3] pin. To configure these devices 

with other supported configuration schemes, select the MSEL[2..0] pins according to 

the MSEL settings in Table 9–7".
