a retransfer, is judged to have been completed, and the TEND bit in SSR is set to 1. If the TIE
bit in SCR is enabled at this time, a TXI interrupt request is generated.
If data transfer by the DTC * by means of the TXI source is enabled, the next data can be
written to TDR automatically. When data is written to TDR by the DTC * , the TDRE bit is
automatically cleared to 0.
