DescriptionResetTypeNameBit/Field
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 ready to 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 fields
in the CANIFnARBn registers, the XTD and DIR bits in the CANIFnARB2
register, or the DLC field in the CANIFnMCTL register.

Extended Identifier
0: An 11-bit Standard Identifier is used for this message object.
1: A 29-bit Extended Identifier is used for this message object.
0R/WXTD14
Message Direction
0: Receive. When the TXRQST bit in the CANIFnMCTL register is set,
a remote frame with the identifier of this message object is received.
On reception of a data frame with matching identifier, that message is
stored in this message object.
1: Transmit. When the TXRQST bit in the CANIFnMCTL register is set,
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=1).
