`data`	Each data message carries up to 8 bytes of data or payload. This member is irrelevant for remote messages, since these do not carry data.
`dlc`	The data length code indicates the number of data bytes in data messages. It is irrelevant in remote messages.
`eid`	The extension identifier specifies the 18 least significant bits of the identifier of an extended message. It is irrelevant for standard messages.
`ide`	The identifier extension specifies whether the message is a standard message (0) or an extended messages (1).
`rtr`	The remote transmission request specifies whether the message is a data message (0) or a remote messages (1).
`sid`	The standard identifier is the identifier of a standard message. In case of an extended message, this member specifies the 11 most significant bits of its identifier.
`xid`	The entire 29-bit identifier, which is relevant only for extended messages.
