wake up signal will go to tri-state condition. In case of an angle comparison with a result below the threshold, the signal
will remain in tri-state condition. After switching on AV
maximum accuracy. A WAKE signal cannot be expected until the end of this period.
WAKE Interface
An open drain NMOS structure is used in the WAKE pad. In order to generate a clear output signal level, a pull up
resistor is required. The pad can drive 4mA.
