4.5 FT245 Asynchronous FIFO Interface Mode Description
The FT2232H can be configured as a dual channel asynchronous FIFO interface. This mode is similar to
the synchronous FIFO interface with the exception that the data is written to or read from the FIFO on
the falling edge of the WR# or RD# signals.
This mode does not provide a CLKOUT signal and it does not expect an OE# input signal. The following
diagrams illustrate the asynchronous FIFO mode timing.
