I'm using the ft2232h in sync fifo mode to do some kind of 'streaming'
data to an fpga. Writing in one thread, reading in another.
In some circumstances, I would like to interrupt this data
flow as quickly as possible and send some out-of-band data to the
fpga. Unfortunately, the data that is still in the ft2232h output
fifo must be written to the fpga before this out-of-band data is seen
by the fpga.
So, the question is: Is it possible to clear the ft2232h output fifo?
Another question: According to the data sheet the output fifo has
a depth of 4kBytes. In my experiments, it only buffers 1kB - is this
a configuration issue, is the datasheet wrong, or am I missing
something?
Thanks, Thomer
