Go-to-Sleep mode is the transitional mode of the device from any state to sleep. In this state the driver and receiver are disabled, reducing the current consumption. However, the INH terminal is on allowing the rest of the system to resume normal operation. If the device is held in this state for time ≥ tgo_to_sleep the device transitions to sleep mode and the INH is turned off (high Z).
Entering Go-to-Sleep Mode from standby mode is gated if the WAKERQ flag is set. Once this flag is cleared the transition is no longer gated.
