The following information pertains to Figure 10:
• The Micro-AB receptacle connects the BCM43907 to an external host or device.
• The Micro-AB connector ID pin is connected to the BCM43907 USB2_DSEL pin.
• The BCM43907 GPIO_9 pin is high in order to select the USB 2.0 PHY.
• The PPC line indicates whether the USB 2.0 host controller supports port power control.
• The OVC line is used to indicate an overcurrent condition.
• Standard differential signal lines D+ (DP) and D– (DM) are used for the USB 2.0 interface
