Figure 23.38 shows an operation example when the CAN transmits a data frame or remote frame.
(1) When the TRMREQ bit in the CiMCTLj register (i = 0, 1; j = 0 to 15) is set to 1 (transmit operation
(2) After a CAN transmit operation is completed, the SENTDATA bit in the CiMCTLj register becomes 1
CAN Transmit Timing
requested) while the CAN bus is in an idle state, the TRMACTIVE bit in the CiMCTLj register
becomes 1 (transmitting), the TRMSTATE bit in the CiSTR register becomes 1 (transmitting), and a
CAN transmit operation is started.
(transmit operation completed), the TRMSUCC bit in the CiSTR register becomes 1 (transmit operation
completed), and the SISj bit in the CiSISTR register becomes 1 (interrupt requested).
