1 = A high delta situation has been detected (positive
code change > 4) and the constant output power
function is adjusting.
1 = Constant Output Power function will use attenuate
the BTL output if the PVDD sense circuit returns a code
higher than the target value.
Amount that the Constant Output Power function is
adjusting the signal gain. Value is 2s compliment with
each step equal to 0.1875dB. The approximate range is
+/- 6dB
ADC Modulator Rate
DAC Modulator Rate
Reserved for future use.
1 = bypass DC removal filter
(WARNING DC content can damage speakers)

11 = 100mS
Under Voltage Lock Out
1 = BTL output disabled if PVDD sense circuit returns
code 0
1 = roundup, 0 = truncate for quantizer
1 = disable binomial filter
1 = 4th order binomial filter; 0 = 3rd order
1 = 24-bit Noise Shaper output (pre-quantizer)
0 = 8/9/10-bit quantizer output
