8.3.2.10
The CANTAAK register indicates the successful abort of a queued message, if requested by the
appropriate bits in the CANTARQ register.
1. Read: Anytime
8.3.2.11
The CANTBSEL register allows the selection of the actual transmit message buffer, which then will be
accessible in the CANTXFG register space.
1. Read: Find the lowest ordered bit set to 1, all other bits will be read as 0

Figure 8-13. 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.
MSCAN Transmitter Message Abort Acknowledge Register (CANTAAK)
MSCAN Transmit Buffer Selection Register (CANTBSEL)
The CANTAAK register is held in the reset state when the initialization
mode is active (INITRQ = 1 and INITAK = 1).
