Following a power-on reset or a USB reset the FT232R will scan its internal EEPROM and read the USB
configuration descriptors stored there. The default values programmed into the internal EEPROM in the
FT232RQ used on the MM232R are shown in Table 8.1.

Notes
FTDI default VID (hex)
FTDI default PID (hex)
A unique serial number is generated and programmed into
the EEPROM during final test of the MM232R module.
Enabling this option will make the device pull down on the
UART interface lines when the power is shut off (PWREN#
is high).
Returns USB 2.0 device description to the host. Note: The
device is be a USB 2.0 Full Speed device (12Mb/s) as
opposed to a USB 2.0 High Speed device (480Mb/s).
Taking RI# low will wake up the USB host controller from
suspend.
Enables the high drive level on the UART and CBUS I/O
pins.
Makes the device load the CVP driver interface for the
device.
Default configuration of CBUS0 – Transmit LED drive.
Default configuration of CBUS1 – Receive LED drive.
Default configuration of CBUS2 – Power enable. Low after
USB enumeration, high during USB suspend.
Default configuration of CBUS3 – Power enable. Low after
USB enumeration, high during USB suspend.
Default configurations of CBUS4 – Low during USB
suspend.
Signal on this pin becomes TXD# if enable.
Signal on this pin becomes RXD# if enable.
Signal on this pin becomes RTS if enable.
Signal on this pin becomes CTS if enable.
Signal on this pin becomes DTR if enable.
Signal on this pin becomes DSR if enable.
Signal on this pin becomes DCD if enable.
Signal on this pin becomes RI if enable.
