Hello,
I plan to use a FT2232H for fast communication (Sync FIFO mode) with my application in FPGA.
I would also use it to update occasionally the configuration memory of the FPGA through JTAG.
The FPGA will be a XP2-17 from Lattice semiconductors.
I read in the datasheet that when you swith the FT2232H to Sync FIFO mode, resources from channel B are also used.
But I did not find what happens with the I/Os from channel B : tristated, tied to zero or tied to one.
Has anyone experience with this mode of FT2232H? What is the behavior of the channel B I/Os?
Another question I have not found an answer. Can I use channel B as a JTAG port if the channel A is disabled? Is it possible to disable the Sync FIFO mode on channel A?
Thank you in advance for your pratical feedbacks.
