Functional Description

This section provides a detailed description of the functionality implemented in the FlexRay block.

30.6.1

Message Buffer Concept

The FlexRay block uses a data structure called

message buffer

to store frame data, configuration, control,

and status data. Each message buffer consists of two parts, the

message buffer control data

and the

physical

message buffer.

The message buffer control data are located in dedicated registers. The structure of the

message buffer control data depends on the message buffer type and is described in

Section 30.6.3,

“Message Buffer Types

”. The physical message buffer is located in the FRM and is described in

Section 30.6.2, “Physical Message Buffer

30.6.2

Physical Message Buffer

All FlexRay messages and related frame and slot status information of received frames and of frames to
be transmitted to the FlexRay bus are stored in data structures called

physical message buffers

. The

physical message buffers are located in the FRM.The structure of a physical message buffer is depicted in

.

A physical message buffer consists of two fields, the

message buffer header field

and the

message buffer

data field

. The message buffer header field contains the

frame header

, the

data field offset

, and the

slot

status

.The message buffer data field contains the

frame data

.

The connection between the two fields is established by the

data field offset

.

Figure 30-99. Physical Message Buffer Structure

30.6.2.1

Message Buffer Header Field

The message buffer header field is a contiguous region in the FRM and occupies ten bytes. It contains the
frame header, the data field offset, and the slot status. Its structure is shown in

. The physical

start address

SADR_MBHF

of the message buffer header field must be 16-bit aligned.

30.6.2.1.1

Frame Header

The frame header occupies the first six bytes in the message buffer header field. It contains all FlexRay
frame header related information according to the

FlexRay Communications System Protocol
