Bit Bang Modes for the FT232R and FT245R  
1.2  
Asynchronous Bit Bang Mode  
Asynchronous Bit Bang mode is the same as BM-style Bit Bang mode. Any data written to the  
device in the normal manner will be self-clocked onto the data pins which have been configured as  
outputs. Each pin can be independently set as an input or an output. The rate that the data is  
clocked out at is controlled by the Baud rate generator.  
For the data to change there, has to be new data written and the Baud rate clock has to tick. If no  
new data is written to the device, the pins will hold the last value written.  
When Asynchronous Bit Bang mode is enabled the IO signal lines are configured as follows:

In the case of the FT232R, any of CBUS0, CBUS1, CBUS2 or CBUS3 can be configured to bring  
out the internal RD# or WR# strobes when the device is in Asynchronous Bit Bang mode, this is  
the same as the Enhanced Asynchronous Bit Bang mode of the FT2232 device. Alternatively, the  
CBUS pins can be used to provide clock signals by setting the appropriate values in the EEPROM.  
The CBUS must be configured in the FT232R EEPROM. This option is not available for the  
FT245R.
