Data Length Code
Specify the number of data bytes this message object contains. Valid
values are 0–8. The CAN controller updates a receive message object's
data length code after each reception to reflect the number of data bytes in
the current message.
Direction
Specify whether this message object is to be transmitted or is to receive a
message object from a remote node.
0 = receive
1 = transmit
Extended Identifier Used
Specify whether this message object's identification registers contain an
extended (29-bit) or a standard (11-bit) identifier.
0 = standard identifier
1 = extended identifier
Reserved; for compatibility with future devices, write zeros to these bits.
