SYNC

COB-ID
: 0x80
The message of the SYNC object is always fixed as the format
described above. The COB-ID of the SYNC object can be changed
arbitrarily. It complies with the producer/consumer relationship.
Step 15. After transmitting the SYNC object, the 1st RxPDO is triggered. The
DI value is also changed at the same time. Hence, users can receive the 1st
TxPDO from CAN-8423.
