Figure 14. Timing Characteristics (BGE

→ BUS)

In NORMAL and RECEIVE-ONLY mode the transmitter drives on the bus Idle in case no data are transmitted. In STANDBY, GO-TO-SLEEP and

SLEEP mode the transmitter drives Idle_LP on the bus pins. In POWER-OFF mode the bus pins shows Idle_HZ.

9.10 Receiver

The Receiver generates from the FlexRay differential bus voltage a digital signal on the RxD and RxEN pins. RxD shows the data (Data0 and

Data1) and RxEN shows the bus idle and activity status received on the bus pins. The Receiver is only active in NORMAL and RECEIVE-ONLY

mode.
