INFINITE ZERO DETECT
Setting the IZD register bit will enable the internal Infinite Zero Detect function:
Table 21 IZD Register
With IZD enabled, applying 1024 consecutive zero input samples to a stereo input channel on any
DAC will cause that stereo channel output to be muted. Mute will be removed as soon as either of
those stereo channels receives a non-zero input.
