In a combined message, each read or write begins with a START and the slave address. After the first
START, these are also called repeated START bits; repeated START bits are not preceded by STOP bits,
which is how slaves know the next transfer is part of the same message.

8.2 USB Battery Charging Detection
A recent addition to the USB specification
(http://www.usb.org/developers/devclass_docs/BCv1.2_011912.zip) is to allow for additional charging
profiles to be used for charging batteries in portable devices. These charging profiles do not enumerate
the USB port of the peripheral. The FT200XD device will detect that a USB compliant dedicated charging
port (DCP) is connected. Once detected while in suspend mode a battery charge detection signal is
provided to allow external logic to switch to charging mode as opposed to operation mode.
Figure 8.2 USB Battery Charging Detection
To use the FT200XD with battery charging detection the CBUS pins must be reprogrammed to allow for
the BCD Charger output to switch the external charger circuitry on. The CBUS pins are configured in the
