    Lawrence,

    No, the WAKE pin responds to a transition from one state to another, not the state of the pin itself. So having it high or low will not affect the device mode, but if the device is in sleep mode and WAKE sees a low-to-high or high-to-low transition, then the device will detect a wake event and transition into Standby mode.
