[7] The TEND bit in SSR is not set for a frame for which an error signal indicating an abnormality is received.
[8] If an error signal is not sent back from the receiving end, the ERS bit in SSR is not set.
[9] If an error signal is not sent back from the receiving end, transmission of one frame, including 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.
