EP3C16F256 Configuration

[Altera_Forum]

Hello, 

I have my configuration running on a DE0 board but I planned on using the EP3C16F256 in the actual application.  I am confused on how to configure the EP3C16F256, does it not support AS configuring with an EPCSx device?  Chapter 9 of the handbook seems to indicate so.  Thanks   Rich

which portion of the doc are you referring to? note that Table 9-10 applies to AP not AS configuration 

 the mention device should support AS

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.  Perhaps this means that the AS fast POR at 3-2.5V is not supported but it is at 3.3V???   So there is no MSEL[3] pin but all the configurations show it used....   Thanks  Rich

right, without MSEL[3] you can do AS with standard POR at 3.3V or 2.5/3.0V or AS with fast POR only at 2.5/3.0V (but not at 3.3V). that's shown in Table 9-7

yes, i guess the documentation doesn't really spell that out
