Figure 16-69 shows the processing to skip resumption of transmitting a message that was stopped
when transmission of an ABT message buffer was aborted.
Figure 16-69:
Transmission Abort Processing (Normal Operation Mode with ABT)
Cautions: 1. Do not set any transmission requests while ABT transmission abort processing
is in progress.
2. Make a CAN sleep mode/CAN stop mode transition request after ABTTRG is
cleared following the procedure shown in Figure 16-69 or Figure 16-70. When
clearing a transmission request in an area other than the ABT area, follow the
procedure shown in Figure 16-67.
