Queued Serial Multi-Channel Module
*Reads access the RDRx; writes access the TDRx.
During SCIx initialization, two bits in the SCCxR1 should be written last: the transmitter enable (TE) and
receiver enable (RE) bits, which enable SCIx. Registers SCCxR0 and SCCxR1 should both be initialized
at the same time or before TE and RE are asserted. A single half-word write to SCCxR1 can be used to
initialize SCIx and enable the transmitter and receiver.
15.7.2
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 transfer. 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 follows:
where SCxBR is in the range of 1 to 8191.
