when the transmission of an ABT message buffer was aborted.

Clear TRQ bit of message
buffer undergoing
transmission.
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 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.
