1) This module supports inter-cut advertisements during playback of a track, so that it can meet some special
needs for some applications.
2) After sending the command 0x13, the system will save the ID V3 information of the track being played and
pause, and then it will play the specified inter-cut track (advertisement). When the inter-cut track is finished,
the system will go back and continue to play the track that was interrupted until to the end.
3) The setting method is build a folder named “ADVERT” in the storage device and put the tracks (ads) you
need in the folder and name the files as “0001 .mp3/wav”, 0002.mp3/wav.
4) If you send an inter-cut command when the module is at Pause status or Stop status, it will not work and
there will be returned error information. In the course of an inter-cut, you can continue to intercut the other
tracks (ads). When the last inter-cut track goes to the end, the systems till goes back to the ID V3 position
saved at the first time.
