3.4.7 FT2232H Pins Configured as a CPU-style FIFO Interface
The FT2232H channel A or channel B can be configured in a CPU-style FIFO interface mode which allows
a CPU to interface to USB via the FT2232H. This mode is enabled in the external EEPROM.
When configured in this mode, the pins used and the descriptions of the signals are shown in Table 3.10
