4.13 FT2232H Mode Selection
When in FT245 FIFO mode, the FT_SetBitMode command can be used to select either Synchronous FIFO (FT_SetBitMode = 0x40) or Asynchronous FIFO mode.
Application Note AN_130
FT2232H Used In An FT245 Style Synchronous FIFO Mode
Цитата
Next send command FT_SetBitMode(Mask, 0x40) to the FTDI driver to switch the FT2232H to FT245 Synchronous FIFO mode (this mode uses the RX & TX buffer of port B, so port B cannot be used for any other purpose in this mode).

ucMode Mode value. Can be one of the following:
0x0 = Reset
0x1 = Asynchronous Bit Bang
0x2 = MPSSE (FT4232H, FT2232H and FT2232 devices only)
0x4 = Synchronous Bit Bang (FT4232H, FT2232H, FT232R, FT245R and FT2232 devices only)
0x8 = MCU Host Bus Emulation Mode (FT4232H, FT2232H and FT2232 devices only)
0x10 = Fast Opto-Isolated Serial Mode (FT4232H, FT2232H and FT2232 devices only)
0x20 = CBUS Bit Bang Mode (FT232R devices only)
0x40 = Single Channel Synchronous 245 FIFO Mode (FT2232H devices only)
Удачи.
