EP3C16 FPP Configuration

I'd like to use FPP configuration with the EP3C16. Looking at the pinout tables only the F484/U484 packages have an MSEL[3] pin. Are these the only packages that support FPP? The handbook indicates no such restriction, in fact, suggests that only the E144 package precludes FPP. What gives?

    The secret of the MSEL[2..0] configuration is, that MSEL[3] is bonded to MSEL[2] internally. The remaining MSEL codes are shown in the below table. (I guess, this could be told clearer in the hardware handbook)

    I'm a bit confused myself. How do I interpret this table (attached)?

    I don't understand your question. There are two codings of the MSEL[2..0] configuration dedicated to FPP: "110" for 2.5 to 3.3 V and "111" for 1.5 to 1.8V.
