Programming Reference

Set the audio playback volume. Volume level can be set from 0 (minimum) to 7 (maximum).
If the vol command is not used in the program, the volume defaults to the maximum (7).

Code Example



Set the audio playback volume to level 5.


Set the audio playback volume to the value stored in M0.

When setting the volume level equal to a register, the upper most bit in the register will be ignored.
For example, if you set vol=M2 and M2 contains 15 (1111b), then the volume will be set to 7 (0111b).
