MSEL = "1111" on Cyclone IV GX

hi

is there any known prevention on Cyclone IV GX, to connect MSEL pins to value = "1111"?

(connected correctly to VCCA = 2.5V)

Best regards

    it doesn't look like MSEL == 1111 is a legal configuration

    what scheme are you trying to use?

    hi

    it seems illegal, I'm trying to understand if it is a mode i should prohibit, cause it can cause the fpga to wake up its configuration pins in an Unknown state.
