15.7.1
The SCI programming model includes the QSMCM global and pin control registers and the DSCI
registers.
The DSCI registers, listed in
data registers. All registers may be read or written at any time by the CPU. Rewriting the same value to
any DSCI register does not disrupt operation; however, writing a different value into a DSCI register when
the DSCI is running may disrupt operation. To change register values, the receiver and transmitter should
be disabled with the transmitter allowed to finish first. The status flags in register SCxSR can be cleared
at any time.
