B The Enable line has been asserted for >= 5ms. The regulator needs 5ms for the on board power supply to settle. C The Head Unit releases the Reset line allowing the DC to begin the initialization. T1 >= 5ms T2 >= 0ms. The Reset line can be released anytime after the Enable line has been asserted for >= 5ms. 2.3.2 Shutdown ENABLE RESET LVI T3 T4 A B C Item Description A Head Unit needs to shut down before the DC has completed the shutdown sequence. Head Unit asserts the LVI line. B Head Unit then waits >=5ms for the DC to shutdown internal sw components. The Head Unit asserts the Reset line. C At this point, both the LVI and Reset lines are being asserted. The Head Unit can now remove the Enable line at any time. T3 >= 5ms
Visteon Electronics Nissan Bluetooth Voice DC UART SRD Version 3.4 November 21st, 2011 Page 15 of 105 Visteon & Nissan Confidential T4 >=0ms. The Enable line can be released anytime after the LVI line has been asserted for >= 5ms. 2.3.3 Reset This timing diagram is used to show the timing required to execute the sequence “Request for Reset”. This timing diagram is used to show the timing required to execute the Reset required during any reflash operation. 2.4 Radio Mute Pin Not used. Item Description A Head Unit asserts the Reset line. B Head Unit releases the Reset line. T1 >= 800ms.
Visteon Electronics Nissan Bluetooth Voice DC UART SRD Version 3.4 November 21st, 2011 Page 16 of 105 Visteon & Nissan Confidential 2.5 LVI Pin. Discussion Point. The LVI pin is used for the HU to indicate to the DC that a low voltage event is happening and an abrupt termination of the 3.3V power supply is expected. T1 is the time for between LVI input is to toggled and when the 3.3V supply drops to below 3.1V. Visteon desires this to be ≥ 20 mSec, but is it understood this is not feasible in HU design. LVI pin is pulled low in such a way as to maximize the time T1 before power supply and or reset line get pulled due to low battery condition at HU power supply. Note: Enable and Reset remain high for at least T1 seconds after LVI signal goes low.

Visteon Electronics Nissan Bluetooth Voice DC UART SRD Version 3.4 November 21st, 2011 Page 18 of 105 Visteon & Nissan Confidential 4 UART Protocol The low level protocol is defined in the reference specification 28330 NDS00 AVC System Comm Spec1.pdf. The HU shall be the AV Unit control station and the DC shall be the subsidiary machine. The Protocol will be implemented without a physical layer, and both the DC and HOos shall operate at 3.3V. Both HU and DC shall implement all features and modes (ie conversation mode) of the protocol as defined. A maximum Baud rate of 38.4 kbps shall be supported. While in normal operations, the Baud rate shall be 9600 bps. 38.4 kbps shall be supported for reflash operations.

This indicates OS and UART are up and running. If this is not received in T1 seconds, HU should strobe reset line again.2. When the HeartBeat.HeadUnit is received by the DC, the DC start the Vehicle Config sequence. DC will continue to send HearBeat.BTCard messages to the Head Unit until a reply is sent.3. The default configuration will be Panasonic if the value for Head Unit ID in the Vehicle.Config.Set message is undefined.4. If the Language Change sequence is run, the Initialization time will increase by up to the maximum time called out in the sequence. This needs to be added to the T2 time as it will increase the time it takes for the DC to be fully initialized and ready to be used.5. Only after FullRun is sent will the DC be able to accept any button press messages. All button press messages will be ignored before this.6. These messages are for the Panasonic DA onlyNotes:The Language Change sequence has been removed from the Initialization Sequence. If a Language Change is called during Initialization, then the timing to be fully initialized and ready for button presses will increase by the Language Change timing. Heartbeat messages are sent continuously throughout the operations of the DC. The HU should not work off of the number of HeartBeat messages received during start up. The time out is to be used to determine the state of the DC during initialization.T1 = TTimeToBootToFirstHeartbeatMessage = 15 seconds.The maximum time it will take the DC to boot up to send the first HeartBeat message (From the time that power is applied, the Enable line asserted, Reset and LVI not asserted). If this time is exceeded, it is expected that the HU will reset the DC and perform the Mismatched Baud Rate sequence as T2 = TTimeToFinishInitAfterFirstHeartbeat= 6 seconds.The maximum time it will take the DC to report that it is in the Full Run state and can begin to process button presses. If this time is exceeded, it is expected that the HU will reset the DC.4

Power.RequestForResetHeartbeat.BTCardReset Line should be held low a m inim umof 800 ms to ensure DC reset occurs. Note: Reset Line should be held low a minimumof 800 ms when HU requests reset for at anytime other than Startup ie: if Heartbeat is lost This indicates O M AP O S is running and UART is up and running. If this is not received in 10 seconds, HU should strobe reset lineagain.

Please use the Spec IT Master in conjunction with these rules below. • Meter General Rules o Any meter messages that also have a head unit comparable message, they should be sent is succession to each other so that the visual cue from the User will appear that they appeared at the same time. o The HF, VR and SMS messages required an State=End message to dismiss this message from the meter. SMS and HF messages can cover the VR message. When the HF or SMS message in front of it is ended, the VR message can still be present unless it is ended also. o Audio Warning messages do not have an End message and are just sent when required. No further management of them is necessary. o Disc messages do not have an End message. They are sent and the Meter will handle their display lifetime. • Session definition for sending MCAN NBUS messages o VR, HF and SMS messages.  Start of the MCAN Session. The message below defines the Start of the MCAN Session. MCAN messages sent over NBUS AFTER this message is successfully sent will be sent on the MCAN bus for the meter to display: • VR and HF: HU→DC – <Audio.TelPermit.Start> • Disc: HU→DC – <Audio.BTPermit.RequesttoStart> • SMS: DC→HU – < Power.Initialization.Full Run>  End of the MCAN Session. The message below defines the End of the MCAN Session. MCAN messages sent over NBUS after this message is successfully sent will NOT be sent on the MCAN bus. Any MCAN messages required to dismiss DC MCAN Meter messages must be sent before the end of the session: • VR and HF: DC→HU: <Audio.TelInterrupt.End > • Disc: HU→DC <Audio.BTPermit.RequestToEnd> • SMS: HU→DC <Power.Shutdown.Request> o Audio Warning (AW) messages  Start of the MCAN Session. The message below defines the Start of the MCAN Session. MCAN messages sent over NBUS AFTER this message is successfully sent will be sent on the MCAN bus for the meter to display: • HU→DC: <AudioTelPermit.Start> • HU→DC: < Audio.BTPermit.RequesttoStart >  End of the MCAN Session. The message below defines the End of the MCAN Session. MCAN messages sent over NBUS after this message is successfully sent will NOT be sent on the MCAN bus.: • DC→HU: <Audio.TelInterrupt.End > • DC→HU: < Audio.BTInterrupt.End> • MCAN VR Messaging o The Audio Warning message shall only be sent once per VR session after the first Startmessage is sent with the default parameters. o A VR Session is defined as when a Speaking and/or Listening and/or Manual mode and/or off(HF_mode) session is followed by a Clearing of VR Banners. o The GOM module should follow the sequence in 50-4 as it does not have audio VR. o VR Session 50-2  Speaking • This will be sent at the start of a VR session when the DC is producing utterances of importance. o VR State Parameters
