Overcurrent warning detect adjustment bypass
Table 23.
The status bit OCWARN is used to warn of an overcurrent condition. When OCWARN is
asserted (set to 0), the power control block forces an adjustment to the modulation limit
(default -3dB) in an attempt to eliminate the overcurrent warning condition. Once the
overcurrent warning volume adjustment is applied, it remains applied until the device is
reset. The overcurrent limit can be changed via register OLIM

Configuration register D (addr 0x03)
Zero-detect mute enable
Table 24.
Setting the ZDE bit enables the zero-detect automatic mute. The zero-detect circuit looks at
the data for each processing channel at the output of the crossover (bass management)
filter. If any channel receives 2048 consecutive zero value samples (regardless of f
that individual channel is muted if this function is enabled.
