2.3 One-Shot Transmission Function
When the TMOM bit of the RSCFDn(CFD)TMCp register is set to 1 (one-shot transmission is enabled), transmission is
performed only once. Even if an arbitration lost or an error occurs, retransmission is not performed.
The result of one-shot transmission can be confirmed by the TMTRF [1: 0] flag in the TMSTSp register. If the
one-shot transmission is successful, the transmit buffer transmission result status is transmission complete: no transmit
abort request (TMTRF [1: 0] flag is “B'10”) or transmission complete: There is a transmit abort request (TMTRF [1: 0]
flag will be “B'11”). If an arbitration lost or an error occurs, abort is completed (TMTRF [1: 0] flag is “B’01”). (Refer
to "2.2 Transmit Abort Function" for transmission completion: There is a transmit abort request (TMTRF [1: 0] flag is
"B'11")). Figure 2-6 shows the operation of one-shot transmission.
