Hi,

This specific part version (AGMFI013) is ordered as a "133 MHz" part (the "AG" in the version.)  Can it support DDR, or does a DS (or DP) version have to be ordered?  It's not 100% clear from the datasheet that DDR Read Command is an optional instruction, but the Ordering Information section does seem to say that DDR and "non-DDR" are separate parts.  If I have to order a new part, can my software determine (through the ID-CFI information?) if the MCU is booting on a DDR-capable NOR QSPI Flash?  I would need to know this to preserve backward compatibility with existing products that only support SDR.

Thanks!

Jean-Luc
