0: Over-Current warning adjustment enabled
1: Over-Current warning adjustment disabled
The OCWARN input is used to indicate an over-current warning condition. When OCWARN
is asserted (set to 0), the power control block forces an adjustment to the modulation limit
(default is -3 dB) in an attempt to eliminate the over-current warning condition. Once the
over-current warning volume adjustment is applied, it remains in this state until reset is
applied. The level of adjustment can be changed via the TWOCL (thermal warning/over
current limit) setting which is address 0x37 of the user defined coefficient RAM.

0: Each channel uses individual post-scale value

1: Each channel uses channel 1 post-scale value
Post-scale functionality can be used for power-supply error correction. For multi-channel
applications running off the same power-supply, the post-scale values can be linked to the
value of channel 1 for ease of use and update the values faster.

Setting of 1 enables the automatic zero-detect mute
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 fs) then
that individual channel is muted if this function is enabled.
