The SCOUT-DX can be reset completely by a hardware reset (pin RST). Additionally
each functional block can be reset separately via register SRES.
If enabled an exchange awake, subscriber awake or watchdog time out can generate a
reset on pin RSTO/SDS2. A hardware reset always generates a reset on pin RSTO/
SDS2 (see figure 75).
