Notes
FTDI default VID (hex)
FTDI default PID (hex)
FTDI default BCD (hex)
A unique serial number is generated and programmed into the
MTP ROM during final test of the module.
Enabling this option will make the device pull down on the I2C
interface lines when the power is shut off (PWREN# is high).
Returns USB 2.0 device description to the host. Note: The
device is 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 I2C and CBUS I/O pins.
Makes the device load the CVP driver interface for the device.
