Figure 18.25 shows the Timing of Transmit Sequence.
(1) If the TrmReq bit in the C0MCTLi register (i = 0 to 15) is set to 1 (Transmission slot) in bus idle state,
(2) If the arbitration is lost after starting transmitting, the TrmActive and TrmState bits are set to 0.
(3) If the transmission is successful without lost arbitration, the SentData bit in the C0MCTLi register is set
(4) When next transmission is performed, set the SentData and TrmReq bits to 0 and check that they are set
the TrmActive bit in the C0MCTLi register and the TrmState bit in the C0STR register are set to 1
(During transmission), and the CAN module starts transmitting a message.
to 1 (Transmission is successfully completed) and TrmActive bit in the C0MCTLi register is set to 0
(Waiting for bus idle or completion of arbitration). When the interrupt enable bits in the C0ICR register
are set to 1 (Interrupt enabled), CAN0 successful transmission interrupt request is generated and the
MBOX and TrmSucc bits in the C0STR register change.
to 0. Then, set the TrmReq bit to 1 by a program.
