PWR OTP 3.3V supply
PWR 1.2V core supply for WLAN
PWR 1.8V–3.3V supply for WLAN. Must be directly
connected to PMU_VDDIO and BT_VDDIO on the
PCB.
PWR 1.2V core supply for BT
PWR 1.8V–3.3V supply for PMU controls. Must be directly
connected to VDDIO and BT_VDDIO on the PCB.
PWR 1.8V–3.3V supply for SDIO pads
PWR IO supply for RF switch control pads (3.3V)
PWR 1.2V supply for HSIC PLL
PWR 1.2V supply for HSIC digital
PWR Baseband PLL supply
PWR 1.2V supply for PCIe PLL
PWR 1.2V supply for PCIE TX and RX
PWR Supply the same voltage to this pin as used for the
PCIe out-of-band signals (that is, PCIE_PME_L). This
would be 1.8V or 3.3V, and cannot be turned off.
