22.5.2.50 Receive Shadow Buffer Index Register (RSBIR)
This register is used to provide and retrieve the indices of the message buffer header fields currently
associated with the receive shadow buffers. For more details on the receive shadow buffer concept, refer
to
Section 22.6.6.3.5, Receive Shadow Buffers Concept

Field
Description
WMD
Write Mode — This bit controls the write mode for this register.
0 update SEL and RSBIDX field on register write
1 update only SEL field on register write
SEL
Selector — This field is used to select the internal receive shadow buffer index register for access.
00 RSBIR_A1 — receive shadow buffer index register for channel A, segment 1
01 RSBIR_A2 — receive shadow buffer index register for channel A, segment 2
10 RSBIR_B1 — receive shadow buffer index register for channel B, segment 1
11 RSBIR_B2 — receive shadow buffer index register for channel B, segment 2
RSBIDX
Receive Shadow Buffer Index — This field contains the current index of the message buffer header field of the
receive shadow message buffer selected by the SEL field. The controller uses this index to determine the
physical location of the shadow buffer header field in the flexray memory. The controller will update this field
during receive operation.The application provides initial message buffer header index value in the configuration
phase.
controller: Updates the message buffer header index after successful reception.
Application: Provides initial message buffer header index.
