These bits are always read as 0. The write value should
always be 0. If 1 is written to these bits, the operation is
not guaranteed.
Transmit Right-Channel Data Assign
Specify the position of right-channel data in a transmit
frame as B'0000 (0) to B'1110 (14).

right-channel data
SITDR as right-channel data
This bit setting is valid when the TDRE bit is set to 1.
When this bit is set to 1, the SITDR bit settings are
ignored.
