Subject: FT2232H bitbang mode: 32 bit bitbang?

Hi,

I have an FT2232H and I would like to bitbang all 32 bits. Is this
possible?

The datasheet seems to suggest that in "async bitbang" mode the high
byte still does strobe thingies.

But in another mode (MPSSE) the high byte becomes "GPIO", so the chip
more or less is able to do this, but then officially the lowest few
bits become the MPSSE interface. 

Then the second question is: can I do this with libftdi?

The plan was simple, like my brother-in-law Phil. But unlike
Phil, this plan just might work.
