Figure 12-11. MSCAN Transmitter Message Abort Acknowledge Register (CANTAAK)
Abort Acknowledge — This flag acknowledges that a message was aborted due to a pending abort request
from the CPU. After a particular message buffer is flagged empty, this flag can be used by the application
software to identify whether the message was aborted successfully or was sent anyway. The ABTAKx flag is
cleared whenever the corresponding TXE flag is cleared.
0 The message was not aborted.
1 The message was aborted.
The CANTAAK register is held in the reset state when the initialization
mode is active (INITRQ = 1 and INITAK = 1).
