The Enable line has been asserted for >= 5ms. The regulator needs 5ms for the on board power supply to settle. The Head Unit releases the Reset line allowing the DC to begin the initialization. >= 5ms >= 0ms.

The Enable line can be released anytime after the LVI line has been asserted for >= 5ms. 2.3.3 Reset Item Description A Head Unit asserts the Reset line. B Head Unit releases the Reset line. T1 >= 800ms. 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.

Visteon Electronics Nissan Bluetooth Voice DC UART SRD 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.

Visteon Electronics Nissan Bluetooth Voice DC UART SRD 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.
