[1] Data being transmitted is lost halfway.
[2] Clear the TIE and TEIE bits to 0 when they are 1.
[3] Transition to module stop state is included.
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.
