LSBFE: LSB First Enable, if cleared, MSB is transferred first, otherwise LSB is transferred
first. Master mode only.
These fields are related to the baud rate:
PBR: baud rate prescaler, used in establishing the
transfer baud rate; the prescaler value is either 2
(00), 3(01), 5(10) or 7(11). Master mode only.
DBR: double baud rate, doubles the SCK baud rate,
but depending on PBR and CPHA, it might alter the
50/50 duty cycle of the clock (see at right). Master
mode only.
BR: baud rate scaler, used in establishing the
transfer baud rate; the baud rate scaler value is
2
[:]
for BR[0:3]< 2, it is 6 for BR[0:3]=2 and
it is 2
[:]
for BR[0:3]> 2. Master mode only.
