3.3.2.53 Receive FIFO B Read Index Register (RFBRIR)
This register provides the message buffer header index of the next available receive FIFO B entry that the
application can read.
NOTE
If the receive FIFO not empty flag FNEBIF is not set, the RDIDX field
points to a physical message buffer that contains invalid data. Only when
FNEBIF is set, does the message buffer indicated by RDIDX contain valid
data.
3.3.2.54 Receive FIFO Message ID Acceptance Filter Value Register
(RFMIDAFVR)
This register defines the filter value for the message ID acceptance filter of the selected receive FIFO. For
details on message ID filtering see Section 3.4.9.5, “Receive FIFO filtering”.

RDIDX
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 Global Interrupt Flag and Enable Register (GIFER).The index wraps back to the first message buffer
header index if the end of the FIFO was reached.
