Figure 19.22 shows the Timing of Transmit Sequence.
(1) If the TrmReq bit in the C0MCTLj register (j = 0 to 15) is set to 1 (transmission slot) in the bus idle state,
(2) If the arbitration is lost after the CAN module starts the transmission, bits TrmActive and TrmState are
(3) If the transmission has been successful without lost in arbitration, the SentData bit in the C0MCTLj

register is set to 1 (transmission is successfully completed) and TrmActive bit is set to 0 (waiting for
bus idle or completion of arbitration). And when the interrupt enable bits in the C0ICR register = 1
(Interrupt enabled), CAN0 successful transmission interrupt request is generated and the MBOX (the
slot number which transmitted the message) and TrmSucc bit in the C0STR register are changed.
