Description added
Before transmitting and receiving data, you should first clear the
TE and RE bits in SCR to 0, then initialize the SCI as shown in
figure 15.5. Do not write to SMR, SCMR, IrCR, or SEMR while
the SCI is operating. This also applies to writing the same data
as the current register contents. …
Description added
Before transmitting and receiving data, you should first clear the
TE and RE bits in SCR to 0, then initialize the SCI as described
in a sample flowchart in figure 15.15. Do not write to SMR,
SCMR, IrCR, or SEMR while the SCI is operating. This also
applies to writing the same data as the current register contents.
