Caution The MDmn0 bit can be rewritten even during operation.
Note When transmit data is written to the SDRmn register while BFFmn = 1, the transmit data is overwritten.

(Note)
However, rewrite it before transfer of the last bit is started, so that it has been rewritten
before the transfer end interrupt of the last transmit data.
