SCI baud rate is programmed by writing a 13-bit value to this field. Writing a value of
zero to SCBR disables the baud rate generator. Baud clock rate is calculated as fol-
lows:
where SCBR[12:0] is in the range of 1 to 8191.
SCCR1 contains SCI configuration parameters, including transmitter and receiver en-
able bits, interrupt enable bits, and operating mode enable bits. SCCR0 can be read
or written at any time. The SCI can modify the RWU bit under certain circumstances.
Changing the value of SCCR1 bits during a transfer operation can disrupt the transfer.
0 = Normal SCI operation, no looping, feedback path disabled.
1 = Test SCI operation, looping, feedback path enabled.
0 = If configured as an output, TXD is a normal CMOS output.
1 = If configured as an output, TXD is an open-drain output.
0 = Short idle-line detect (start count on first one).
1 = Long idle-line detect (start count on first one after stop bit(s)).
0 = Even parity
1 = Odd parity
0 = SCI parity disabled.
1 = SCI parity enabled.
