A message can be removed from the transmit holding buffer by asserting the TxAbort (Bit 1 if TX_MSG#_CTRL_CMD register) flag. The content of a particular transmit message buffer can be removed by setting TxAbort to 1 to request message removal. This flag remains set as long as the message abort request is pending. It is cleared when either the message wins arbitration (TX_MSG interrupt active) or the message is removed (TX_MSG interrupt inactive).
