2.2.1 Transmit Abort Procedure
Figure 2-5 shows the procedure for transmit abort.
【Note】 1. Rewrite the TMCp register in channel communication mode or channel standby mode.
2. Set the transmit TMCp register that satisfies the following conditions to "H'00".
Transmit buffer linked to the transmit/receive FIFO buffer
Transmit buffer assigned to the transmit queue
3. When there is a transmit request in the transmit buffer (the TMTR bit of the TMCp register is “1”), a transmit
abort request can be issued (the TMTAR bit of the TMCp register is “1”).
4. Depending on the timing, the transmission result will be transmission is completed: There is a transmit abort
(the TMTRF[1:0] flag in the TMSTSp register is "B'11"), so if the transmission result is to be determined,
please check not only if the transmission is complete (TMTRF [1:0] flag is "B'01") but also if the
transmission is completed: There is a transmit abort. Please refer to "2.4.3 Processing procedure after
transmission completion and transmit abort completion" for the procedure for confirming transmission
completion and transmit abort completion.
