RXFIE — Receiver Full Interrupt Enable
1 = A receive buffer full (successful message reception) event will
result in a receive interrupt.
0 = No interrupt will be generated from this event.
NOTE: The CRIER register is held in the reset state when the SFTRES bit in
CMCR0 is set.

Transmitter Flag
Register
The Abort Acknowledge flags are read only. The Transmitter Buffer
Empty flags are read and clear only. A flag can be cleared by writing a 1
to the corresponding bit position. Writing a 0 has no effect on the flag
setting. The Transmitter Buffer Empty flags each have an associated
interrupt enablebit in the CTCR register. A hard or soft reset will resets
the register.

ABTAK2–ABTAK0 — Abort Acknowledge
This flag acknowledges that a message has been aborted due to a
pending abort request from the CPU. After a particular message
buffer has been flagged empty, this flag can be used by the
application software to identify whether the message has been
aborted successfully or has been sent. The ABTAKx flag is cleared
implicitly whenever the corresponding TXE flag is cleared.
1 = The message has been aborted.
0 = The message has not been aborted, thus has been sent out.
