4.1
The FT234XD IC on the module contains an embedded MTP ROM, this can be used to specify the USB
descriptors, the functions of the CBUS0 pin, the current drive on each signal pin and the current limit for
the device. These features can be programmed using FTDI’s programming utility FT_Prog. For details on
using FT_Prog, please see the
When programming the MTP ROM please note:
i) The Max Bus Power setting of the MTP ROM should specify the maximum current to be drawn from
the USB host/hub when enumerated. For high-powered USB devices the current limit when
enumerated is between 100mA and 500mA, for low-powered USB devices the current limit is
100mA.
