It is possible to “share” the EEPROM between the FT2232D and another external device such as an MCU.
However, this can only be done when the FT2232D is in its reset condition as it tri-states its EEPROM
interface at that time. A typical configuration would use four bits of an MCU IO Port. One bit would be
used to hold the FT2232D reset (using RESET#) on power-up, the other three would connect to the
EECS, EESK and EEDATA pins of the FT2232D in order to read / write data to the EEPROM at this time.
Once the MCU has read / written the EEPROM, it would take RESET# high to allow the FT2232D to
configure itself and enumerate over USB.
The external EEPROM can be programmed over USB using utility software provided by FTDI. The external
EEPROM is used to enable 245 FIFO, and Fast Opto-Isolated Serial interface modes on each channel.
