The CTFLG register is held in the reset state if the SFTRES bit in
CMCR0 is set.
ABTRQ2 – ABTRQ0 — Abort Request
The software must not clear one or more of the TXE flags in CTFGL and
simultaneously set the respective ABTRQ bit(s).
TXEIE2 – TXEIE0 — Transmitter Empty Interrupt Enable
The CTCR register is held in the reset state if the SFTRES bit in CMCR0
is set.
ABTRQ2
The CPU sets this bit to request that an already scheduled message
buffer (TXE = 0) shall be aborted. The msCAN12 will grant the
request when the message is not already under transmission. When
a message is aborted the associated TXE and the abort acknowledge
flag (ABTAK, see
be set and an TXE interrupt will occur if enabled. The CPU can not
reset ABTRQx. ABTRQx is reset implicitly whenever the associated
TXE flag is set.

For More Information On This Product,
0 = The associated message buffer is full (loaded with a message
1 = The associated message buffer is empty (not scheduled).
0 = No abort request.
1 = Abort request pending.
0 = No interrupt will be generated from this event.
1 = A transmitter empty (transmit buffer available for transmission)
due for transmission).
event will result in a transmitter empty interrupt.
