3 new controls are added. "OVC Autorestart Switch" : controls whether or not the speaker amplifier automatically re-enables after an overcurrent fault condition. "THERM Autorestart Switch" : controls whether or not the device automatically resumes playback when the die temperature recovers from thermal shutdown. "CMON Autorestart Switch" : controls whether or not the device automatically resumes playback when the clock returns after stopping.
Above Auto Restart functions are enabled by default.
