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 DMAC or 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 DMAC or DTC, the
TDRE bit is automatically cleared to 0.
