adjusting volume in a voice macro. Commands for adjusting volume won’t go through the command
buffer; therefore, they will be executed immediately. Below is an example where the volume is
immediately decreased when VP_A starts to play.
If users want to decrease volume after VP_A finishes, the voice macro should be modified as below:
Please note that the commands in a Voice Macro are executed sequentially and all voice macros
shall be ended by PD or FINISH to finish the voice macro. The VPE15100 will show up a warning
message if it detects a voice macro not ended by PD or FINISH.
The example project has some VMs for demo purpose:
Below are the steps of making the POI macro:
Other VMs are done in similar ways.

1. Click on ‘Set CLK CFG’ (D) to set clock source to 4MHz crystal (0x27).
2. Set CFG17 to 0x00 (F) so that registers won’t be updated immediately.
3. Switch to ‘Configuration’ screen; we are going to set a playback path to PWM.
4. Click on ‘007 PLAYBACK MEMORY-> PWM’ (I); a green line for the path will light up.
5. Click on ‘Sub-group selection’ (J); leave ‘Audio Config’ and ‘UPDATE’ checked; uncheck
6. Switch back to ‘Voice Macro’ screen; click on ‘Set All checked group’ (K).
7. Click on the voice prompt ‘FastBeep’ (A).
8. Click on PD (E).
