**Note 27: In Input Mode, these pins are pulled to VCCIO via internal 200K resistors. These can be
programmed to gently pull low during USB suspend ( PWREN# = “1” ) by setting this option in the
EEPROM.
Enabling
MPSSE mode is enabled using Set Bit Bang Mode driver command. A hex value of 2 will enable it, and a
hex value of 0 will reset the device. See application note AN2232-02, “Bit Mode Functions for the
FT2232D” for more details and examples.
The MPSSE command set is fully described in application note AN_108, “Command Processor for
MPSSE and MCU Host Bus Emulation Modes”.
