Figure 18-41:
ABT Message transmit processing
<~Reference>Figure 18-41 shows the processing for a transmit message buffer (MT[2:0] bits of
CnMCONFm register = 000B)
Note:
This processing (normal operation mode with ABT) can only be applied to message buffers 0 to
7. For message buffers other than the ABT message buffers, see <~Reference>Figure 18-40 on
page 845.
Caution
The ABTTRG bit should be set to 1 after the TSTAT bit is cleared to 0.
Checking the TSTAT bit and setting the ABTTRG bit to 1 must be processed
consecutively.
