13.3.2.1
The SCI Baud Rate Register is used by the counter to determine the baud rate of the SCI. The formula for
calculating the baud rate is:
where:
Read: Anytime. 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.
Write: Anytime

SCI baud rate = SCI module clock / (16 x BR)
BR is the content of the SCI baud rate registers, bits SBR12 through SBR0. The baud rate registers
can contain a value from 1 to 8191.
SBR7
SCI Baud Rate Bits — The baud rate for the SCI is determined by these 13 bits.
Note: The baud rate generator is disabled until the TE bit or the RE bit is set for the first time after reset. The

baud rate generator is disabled when BR = 0.
Writing to SCIBDH has no effect without writing to SCIBDL, since writing to SCIBDH puts the data in a
temporary location until SCIBDL is written to.
