To ensure data integrity, no registers of the transmit buffers should be written
to while the associated TXE flag is cleared.
The CTFLG register is held in the reset state if the SFTRES bit 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).

transmission request was successfully aborted due to a pending abort
request
a transmit interrupt is pending while this flag is set.
Clearing a TXEx flag also clears the corresponding ABTAKx flag (see
above). When a TXEx flag is set, the corresponding ABTRQx bit is
cleared (see
The CPU sets an ABTRQx bit to request that a scheduled message
buffer (TXEx = 0) shall be aborted. The msCAN12 grants the request
if the message has not already started transmission, or if the
transmission is not successful (lost arbitration or error). When a
message is aborted the associated TXE and the Abort Acknowledge
flag (ABTAK, see

reset ABTRQx. ABTRQx is cleared implicitly whenever the
associated TXE flag is set.
