Data being transmitted is interrupted.
After exiting software standby
mode, etc., normal CPU transmission
is possible by setting TE to 1, reading
SSR, writing TDR, and clearing TDRE
to 0.
If TIE and TEIE are set to 1, clear
them to 0 in the same way.
Includes module stop mode, watch mode,
subactive mode, and subsleep mode.
