Remark
Figure 20-42 shows the processing for a transmit message buffer (C0MCONFm.MT2 to C0MCONFm.MT0 bits = 000B).
Caution The ABTTRG bit should be set to 1 after the TSTAT bit is cleared to 0. The checking of the
This processing (message transmit processing with ABS) can only be applied to message buffers 0
to 7. For message buffers other than the ABT message buffers, refer to Figure 20-41.
TSTAT bit and the setting for the ABTTRG bit to 1 must be continuous.
