PACKAGE AND THERMAL CONSIDERATION
The device is proposed in a standard surface mount
SOIC28 package. In order to improve the thermal
performances of the SOIC28 package, eight pins are
internally connected to the lead frame and are used for heat
transfer to the printed circuit board.

Normal, Stand-by, and Stop Debug modes
are entered
through special sequence described in the Debug mode
paragraph.
