15:5 : BD - SCI baud divisor select
Divisor:
0x000 --> 1 (bypass divider)
0x001 --> 2
0x002 --> 3
...
0x007 --> 8
...
4:0 : BDFA - SCI baud divisor fine adjust
These bits select the number of clocks inserted in each 32 output cycle frame to achieve
more timing resolution on the average baud frequency shown in the following table.
BDFA[00000] = 0/32 = 0
BDFA[00001] = 1/32 = 0.03125
BDFA[00010] = 2/32 = 0.0625
...
BDFA[10000] = 16/32 = 0.5
...
BDFA[11111] = 31/32 = 0.96875
reset value: 0x0000
The divider can be used to achieve divisor values between 1 and 2047.96875. The baud divi-
sor fine adjust can be used to fine tune the baud rate in 1/32 steps of the divisor.
Use the following formula to calculate the SCI baud rate:
Baud Rate = clksys/(16*(BD+BDFA))
Note: The 16 bit baud divisor value represents the number of system clock cycles of two bit
lengths. The result of a baud measurement(see measurement counter below) can directly be
written to the baud rate register.
