sent out within the time, indicating that the module initialization error, please reset the module's power supply,
and detect hardware connecting;
2).The module initialization data including online devices, such as sending 7E FF 06 3F 00 00 01 xx xx EF, DL
= 0x01 describe only the U-disk online during power-on, Other data are seen as the table below:
U-Disk on-line
TF Card on-line
PC on-line
FLASH on-line
U-disk & TF Card
on-line
3).MCU will not send corresponding control commands until module initialization sending commands or the
module will not process the commands sent by MCU, and will also affect the normal initialization of the
module.

U-Disk finish playback 2nd
TF card finish playback 1st track
TF card finish playback 2nd
Flash finish playback 1st track
Flash finish playback 2nd
1.The module will enter into pause status automatically after being specified playing, if customers need
such application, they can specify track to play ,the module will enter into pause status after finishing
playing ,and wait for the commands sent by MCU.
2 In addition, we opened a dedicated I/O as decoding and pausing status indication. See Pin 16, Busy
1).Output high level at playback status;
2).Output low level at pause status and module sleep;
3. For continuous playback applications, it can be achieved as below, if it finishes the first tracking of the

7E FF 06 3D 00 00 01 xx xx EF
3D ---- U-disk command
00 01 ---- expressed finished playing tracks.
If the external MCU receives this command, please wait 100ms. And then sending the playback command

5. After specifying device, the module play pointer will point to device root directory of the first track,
and enters the pause state, and wait MCU sending track playing command.
