8. FUNCTIONAL DESCRIPTION
sets the attenuation from the maximum volume level in 0.5 dB steps. Thus, maximum volume is 0x0000
and total silence is 0xFEFE.
Note, that after hardware reset the volume is set to full volume. Resetting the software does not reset the
volume setting.
Setting SCI VOL to 0xFFFF will activate analog powerdown mode.
Example: for a volume of -2.0 dB for the left channel and -3.5 dB for the right channel: (2.0/0.5) = 4,
3.5/0.5 = 7 → SCI VOL = 0x0407.
Example: SCI VOL = 0x2424 → both left and right volumes are 0x24 * -0.5 = -18.0 dB
8.7.12 SCI AICTRL[x] (RW)
SCI AICTRL[x] registers ( x=[0 .. 3] ) can be used to access the user’s application program.
