 Voice Data Compression :

Voice File data is stored in the on-chip EPROM as either 4-bits ADPCM or 8-bits PCM/ ULAW format

or 16-bits PCM format. Voice data are stored as 16-bits PCM forma is without compression. The voice

playback quality is best. Voice data stored as 4-bits ADPCM or 8-bits PCM/ ULAW provide 4:2 data

compression to save memory space. But voice playback quality with be lower than 16-bits PCM format.

 Group Options :

User selectable options that affect each individual group are called Group Options. They are:

• Edge or Level trigger.

• Unholdable or Holdable option.

• Re-triggerable or Non-retriggerable option.

• Stop pulse disable or enable.
