SCI Baud Rate divider, a value from 1 to 8191
Refer to the description of the FRAC_SBR bitfield.
Fractional SCI Baud Rate divider, a value from 0 to 7 that is divided by 8
The SBR and FRAC_SBR fields combine to form the divider to determine the baud rate of the SCI. SBR
represents the integer portion of the baud rate divider, and FRAC_SBR represents the fractional portion.
