Figure 20-48 (a) shows processing that does not skip resuming the transmission of a message that was interrupted
when the transmission of an ABT message buffer was aborted.

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 the ABTTRG bit is
cleared (after ABT mode is stopped) following the procedure shown in Figure 20-48 (a) or
(b). When clearing a transmission request in an area other than the ABT area, follow the
procedure shown in Figure 20-46.
