ZCD
Zero-Crossing_Detection. Determines whether zero-crossing detection is used on all
volume control changes to reduce clicks and pops. Disabling zero-crossing detection
allows volume changes to occur immediately.
0 = Enabled
1 = Disabled
6
SLEW
Volume_Slewing._Determines whether volume slewing is used on all volume control
changes to reduce clicks and pops. When enabled, volume changes cause the
MAX97000 to ramp through intermediate volume settings whenever a change to the
volume is made. If ZCD = 1, slewing occurs at a rate of 0.2ms per step. If ZCD = 0, slew
time depends on the input signal. Write a 1 to this bit to disable slewing and implement
volume changes immediately. This bit also activates soft-start at power-on and soft-stop
and power-off.
0 = Enabled
1 = Disabled
