Bit 1: Tail mark transmission flag (MTRF)
When MRKON = 1, bit 1 indicates that a tail mark is being transmitted. MTRF is a read-only bit,
and cannot be modified.

Bit 0: Start flag (STF)
The STF bit controls the start of transfer operations. SCI1 transfer operation is started when this
bit is set to 1.
STF remains set to 1 during transfer and while SCI1 is waiting for a start bit, and is cleared to 0
when transfer ends.

3. Serial data register U (SDRU)
SDRU is an 8-bit read/write register used as the data register for the upper 8 bits in 16-bit transfer
(while SDRL is used for the lower 8 bits).
The data written into SDRU is output to SDRL in LSB-first order. In the replacement process, data
is input LSB-first from the SI
SDRU read/write operations must only be performed after data transmission/reception has been
completed. Data contents are not guaranteed if read/write operations are executed while data
transmission/reception is in progress.
The value of SDRU is undefined upon reset.
