Register. This bit must be set to zero 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.
0
The message object is ignored by the message
handler.
1
The message object is configured and should be
considered by the message handler.

Data length code
0000 R/W
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 to 1000 = Data frame has 0 - 8 data bytes.
1001 to 1111 = Data frame has 8 data bytes.

R/W
0
Message object belongs to a FIFO buffer and is
not the last message object of that FIFO buffer.
1
Single message object or last message object of
a FIFO buffer.

0
This message object is not waiting for
transmission.

The transmission of this message object is
requested and is not yet done

0
At the reception of a remote frame, TXRQST is
left unchanged.
1
At the reception of a remote frame, TXRQST is
set.
