MSCAN Transmitter Message Abort Acknowledge Register
(CANTAAK)
Abort Acknowledge — This flag acknowledges that a message was aborted due to a pending transmission
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).
