[1] 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, but note
that if the DTC
*
has been activated,
the remaining data in DTCRAM will
be transmitted when TE and TIE
are set to 1.
[2] If TIE and TEIE are set to 1, clear
them to 0 in the same way.
[3] Includes module stop mode, watch
mode, subactive mode, and
subsleep mode.
Note: * The DTC function is not
available in the H8S/2695.
