Master Volume Down. Modifies output level on pins L_OUT and R_OUT .
When asserted LO, decreases Master Volume by 1.5 dB/sec. Must be asserted at
least 25 ms to be recognized. When asserted simultaneously with
VOL_UP
, out-
put is muted. Output level modification reflected in indirect register [41].
Master Volume Up. Modifies output level on pins L_OUT and R_OUT . When
asserted LO, increases Master Volume by 1.5 dB/sec. Must be asserted at least
25 ms to be recognized. When asserted simultaneously with
VOL_UP
, output is
muted. Output level modification reflected in indirect register [41].
