SCIBR determines the SCI baud rate. A write to SCIBR[19–23] has no effect without a write to
SCIBR[24–31], since writing to SCIBR[19–23] puts the data in a temporary location until
SCIBR[24–31] is written.
Note:
The formula for calculating the baud rate is: SCI baud rate = SCI system clock/(16
×
SBR).
Note:
The baud-rate generator is disabled until the SCICR[TE] bit or the SCICR[RE] bit is
set for the first time after reset. The baud-rate generator is disabled when SBR = 0.
