2.1 Message Transmit Function
This is the function to send data frames or remote frames.
A message can be sent by setting a transmit request in the transmit buffer (the TMTR bit of the TMCp register is
“1”).
The transmission result can be confirmed by the TMTRF [1: 0] flag in the corresponding TMSTSp register. If the
transmission is successful, the transmission is completed: no transmit abort request (the TMTRF [1: 0] flag is “B'10”),
or the transmission is completed: transmit abort required (the TMTRF [1: 0] flag is “B'11”). About the transmission is
completed: transmit abort request (the TMTRF [1: 0] flag is "B'11"), refer to "2.2 Transmit abort function")
For each transmit buffer, interrupt enable/disable when transmission is completed can be set with the TMIEp bit of
the TMIECy register.
Figure 2-1 shows the operation of the transmit buffer.
