Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Message Valid
0: The message object is ignored by the message handler.
1: The message object is configured and will be considered by the
message handler within the CAN controller.
All unused message objects should have this bit cleared during
initialization and before clearing the Init bit in the CANCTL register.
The MsgVal bit must also be cleared before any of the following bits
are modified or if the message object is no longer required: the ID bit
fields in the CANIFnARBn registers, the Xtd and Dir bits in the
CANIFnARB2 register, or the DLC bits in the CANIFnMCTL register.
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.
Message Direction
0: 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: Transmit. On TxRqst, the respective message object is transmitted
as a data frame. On reception of a remote frame with matching identifier,
TxRqst bit of this message object is set (if RmtEn=1).
