It can operate in 10 host or client mode. It supports Battery Charging Specification, rev 11 1.2 (BC1.2) with Standard/Charging/Dedicated downstream port 12 (SDP/CDP/DCP) advertisement when in host mode. In portable device or 13 client mode it starts BC1.2 detection to detect the attached host 14 type.
