[1] Data being transmitted is lost
halfway. Data can be normally
transmitted from the CPU by
setting the TE bit to 1, reading
SSR, writing to TDR, and
clearing the TDRE bit to 0 after
clearing software standby mode;
however, if the DTC has been
activated, the data remaining in
the DTC will be transmitted when
both the TE and TIE bits are set
to 1.
[2] Clear the TIE and TEIE bits to 0
when they are 1.
[3] Setting of the module stop state
is included.
