FT2232C Dual USB UART / FIFO I.C.
5.3 IO Mode Command Hex Values
Enhanced Asynchronous and Synchronous Bit-Bang modes, MPSSE, and MCU Host Bus Emulation modes are
enabled using the D2XX driver command FT_SetBitMode. The hex values used with this command to enable these
modes are as follows-
Mode
Value (hex)
Reset the IO bit Mode
Asynchronous Bit Bang Mode
MPSSE
0
1
2
Synchronous Bit bang Mode
MCU Host bus Emulation
Fast Opto-Isolated Serial Mode
4
8
10
See application note AN2232C-02 “Bit Mode Functions for the FT2232C” for more details and examples.
Note that all other device modes can be enabled in the external EEPROM, and do not require these values to be
configured.
In the case of Fast Opto-Isolated Serial mode sending a value of 10 will hold this device mode in reset, and sending a
value of 0 will release this mode from reset.
