Write: anytime
The SCI baud rate register is used to determine the baud rate of the SCI and to control the infrared
modulation/demodulation submodule.

If only SCIBDH is written to, a read will not return the correct data until
SCIBDL is written to as well, following a write to SCIBDH.
The baud rate generator is disabled after reset and not started until the TE
bit or the RE bit is set for the first time. The baud rate generator is disabled
when (SBR[12:0] = 0 and IREN = 0) or (SBR[12:1] = 0 and IREN = 1).
Writing to SCIBDH has no effect without writing to SCIBDL, because
writing to SCIBDH puts the data in a temporary location until SCIBDL is
written to.
