MsgVal
Message Valid
0 = The Message Object is ignored by the Message Handler.
1 = The Message Object is configured and should be considered by the Message Handler.
Note:
The application software must reset the MsgVal bit of all unused Messages Objects
during the initialization before it resets bit Init (CAN_CON[0]). This bit must also be reset
before the identifier Id28-0 (CAN_IFn_ARB1/2), the control bits Xtd (CAN_IFn_ARB2[14]), Dir
(CAN_IFn_ARB2[13]), or the Data Length Code DLC3-0 (CAN_IFn_MCON[3:0]) are
modified, or if the Messages Object is no longer required.

Xtd
Extended Identifier
0 = The 11-
bit (“standard”) Identifier will be used for this Message Object.
1 = The 29-
bit (“extended”) Identifier will be used for this Message Object.

Dir
Message Direction
0 = Direction is 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.
1 = Direction is 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 (CAN_IFn_CMASK[2]) of this
Message Object is set (if RmtEn (CAN_IFn_MCON[9]) = one).
