Message identifier
29-bit identifier (extended frame)
11-bit identifier (standard frame)
Message direction
Direction = receive.
On TXRQST, a Remote Frame with the identifier of this Message Object is
transmitted. On reception of a Data Frame with matching identifier, that
message is stored in this Message Object.
Direction = transmit.
On TXRQST, the respective Message Object is transmitted as a Data
Frame. On reception of a Remote Frame with matching identifier, the
TXRQST bit of this Message Object is set (if RMTEN = one).
Extend identifier
The 11-bit standard identifier will be used for this message object.
The 29-bit extended identifier will be used for this message object.
Message valid
Remark: The CPU must reset the MSGVAL bit of all unused Messages
Objects during the initialization before it resets bit INIT in the CAN Control
Register. This bit must also be reset before the identifier ID28:0, the control
bits XTD, DIR, or the Data Length Code DLC3:0 are modified, or if the
Messages Object is no longer required.
The message object is ignored by the message handler.
The message object is configured and should be considered by the
message handler.
Reserved
Description
Data length code
Remark: The Data Length Code of a Message Object must be defined the
same as in all the corresponding objects with the same identifier at other
nodes. When the Message Handler stores a data frame, it will write the
DLC to the value given by the received message.
0000 - 1000 = Data frame has 0 - 8 data bytes.
1001 - 1111 = Data frame has 8 data bytes.
reserved
End of buffer
Message object belongs to a FIFO buffer and is not the last message
object of that FIFO buffer.
Single message object or last message object of a FIFO buffer.
