MAXII + PFL + CFI Flash word-programming format?

Another day, another problem! My design uses the PFL in a MAXII to load either a user configuration or factory configuration from a P30 flash via FPP. When programming the flash via JTAG/MAXII/...

Thanks Dave. I will create some states to my FSM that reads the first word from flash to check the byte order. Creating QSYS is not 'easy' for me ;)

What is the difference between RBF and RPD? I'm currently enabling RBF generation via the QII Device Settings dialog.

In previous designs (Cyclone II) I could program via PS simply by shifting out the data byte by byte (LSB first, i think).

Essentally, I want to know whether the PFL grabs the LSByte first when sending the first flash word to the FPGA.
