[1] STBN must be set to LOW 60 µs after EN.

[2] Positive edge on pin STBN sets the wake flag. In the case of a transition to Normal mode the wake flag is immediately cleared.

[3] Setting the wake flag clears the UVVIO, UVVBAT and UVVCC flag.

[4] Hold time of go-to-sleep is less than the minimum hold time.

[5] Hold time of go-to-sleep becomes greater than the minimum hold time.
