FlexRay Module (FLEXRAYV2)
3.2
This section lists and describes the FlexRay module signals, connected to external pins. These signals are
summarized in
3.2.1
This section provides a detailed description of the FlexRay module signals, connected to external pins.
3.2.1.1
The RXD_BG1 signal carries the receive data for channel A from the corresponding FlexRay bus driver.
3.2.1.2
The TXD_BG1 signal carries the transmit data for channel A to the corresponding FlexRay bus driver.
3.2.1.3
The TXEN1# signal indicates to the FlexRay bus driver that the FlexRay module is attempting to transmit
data on channel A.
3.2.1.4
The RXD_BG2 signal carries the receive data for channel B from the corresponding FlexRay bus driver.
