Note:
1. GPIO_0 and WL_DEV_WAKE signals are selected by using software.
2. USB_VBUS_PRESENT indicates that USB30D is selected.
3. SDIO_PADVDDIO = 1 (not in straps table) is set to 3.3V by default for all packages.
4.GPIO_7 can be used as WL_LED in WLBGA packages.
5. USB_MDx/HSIC_MDx MDIO is the interface of USB1.0/2.0/3.0 PHY or of HSIC PHY (depending on the strap option).
