NOTE
If an external device drives a positive voltage to the signal pads and the CC3200 device is
not powered, DC current is drawn from the other device. If the drive strength of the external
device is adequate, an unintentional wakeup and boot of the CC3200 device can occur. To
prevent current draw, TI recommends any one of the following:
• All devices interfaced to the CC3200 device must be powered from the same power rail
as the chip.
• Use level-shifters between the device and any external devices fed from other
independent rails.
• The nRESET pin of the CC3200 device must be held low until the VBAT supply to the
device is driven and stable.
