Hi!

Would it be possible to add an option in the SPI VVC of which way to shift in and shift out data? Most usecases use MSB first, but some niche cases do require LSB first. I don’t have a good overview, but I might give it a go myself, if this is a feature that would be considered to be implemented 🙂
