Figure 19.21 Timing of Transmit Sequence
19.15.2 Transmission
Figure 19.21 shows the Timing of Transmit Sequence.
(1) If the TrmReq bit in the CiMCTLj register (i = 0, 1, j = 0 to 15) is set to 1 (transmission slot) in the bus
(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 CiMCTLj

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 CiICR register = 1
(interrupt enabled), CANi successful transmission interrupt request is generated and the MBOX (the
slot number which transmitted the message) and TrmSucc bit in the CiSTR register are changed.
