Enable Message Object
0 - message object is disabled => the message object is free for a new
emission or reception.
1 - message object is enabled.
This bit is resetable by re-writing the CANCONCH of the corresponding
message object.
Reserved
The values read from this bit is indeterminate. Do not set this bit.
Status of Interrupt by Message Object
0 - no interrupt.
1 - IT turned on. Reset when interrupt condition is cleared by user.
SIT14:8 = 0b 0000 1001 -> IT’s on message objects 11 and 8.
