There are reserved bits. These bits are always read as ‘0’ and must always be written
with ‘0’.
Message Valid
1 = The Message Object is configured and should be considered by the Message
Handler.
0 = The Message Object is ignored by the Message Handler.
Note: The application software must reset the MsgVal bit of all unused Messages
Length Code DLC3-0 are modified, or if the Messages Object is no longer required.
Extended Identifier
1 = The 29-bit (“extended”) Identifier will be used for this Message Object.
0 = The 11-bit (“standard”) Identifier will be used for this Message Object.
Message Direction
1 = Direction is transmit
0 = Direction is receive

bit must also be reset before the identifier Id28-0, the control bits Xtd, Dir, or the Data
reception of a Remote Frame with matching identifier, the TxRqst bit of this Message
Object is set (if RmtEn = one).
On reception of a Data Frame with matching identifier, that message is stored in this
Message Object.
On TxRqst, a Remote Frame with the identifier of this Message Object is transmitted.
On TxRqst, the respective Message Object is transmitted as a Data Frame. On
