Read Index — This field provides the message buffer header index of the next available receive FIFO entry that
the application can read. The FlexRay module increments this index when the application writes to the FNEBIF
flag in the
header index if the end of the FIFO was reached.

If the receive FIFO not empty flag FNEAIF is not set, the RDIDX fields
points to an physical message buffers that is invalid. Only when FNEAIF is
set, the message buffer indicated by RDIDX contains valid data.
If the receive FIFO not empty flag FNEBIF is not set, the RDIDX fields
points to an physical message buffers that is invalid. Only when FNEBIF is
set, the message buffer indicated by RDIDX contains valid data.
