A single half-word write to SCCxR1 can be used to initialize SCIx and enable the trans-
mitter and receiver.
SCCxR0 contains the SCIx baud rate selection field and two bits controlling the clock
source. The baud rate must be set before the SCI is enabled. The CPU can read and
write SCCxR0 at any time.
Changing the value of SCCxR0 bits during a transfer operation can disrupt the trans-
fer. Before changing register values, allow the SCI to complete the current transfer,
then disable the receiver and transmitter.
SCCxR1 contains SCIx configuration parameters, including transmitter and receiver
enable bits, interrupt enable bits, and operating mode enable bits. The CPU can read
or write this register at any time. The SCI can modify the RWU bit under certain
circumstances.
Changing the value of SCCxR1 bits during a transfer operation can disrupt the trans-
fer. Before changing register values, allow the SCI to complete the current transfer,
then disable the receiver and transmitter.

SCI baud rate. The SCI baud rate is programmed by writing a 13-bit value to this field. Writing a
value of zero to SCxBR disables the baud rate generator. Baud clock rate is calculated as
