Caution 1.
To request for aborting transmission, clear FCNnMmCTL.FCNnMmTRQF, but
not FCNnMmCTL.FCNnMmRDYF.
Caution 2. Before making a sleep mode transition request, confirm that no transmission
request that uses this processing is remaining.
Caution 3. FCNnCMCLCTL.FCNnCMCLSSTS can be periodically checked by a user
application or can be checked after the transmit completion interrupt.
Caution 4. Do not execute any new transmission request including transmission in other
message buffers while transmission abort processing is in progress.
