DAC Bias boost
0 = Disable
1 = Enable
When DAC Bias boost is enabled, the bias
selected by DACBIAS_SEL and
DACVMID_BIAS_SEL are both doubled.
DAC bias current select
00 = Normal bias
01 = Normal bias x 0.5
10 = Normal bias x 0.66
11 = Normal bias x 0.75
DAC VMID buffer bias select
00 = Normal bias
01 = Normal bias x 0.5
10 = Normal bias x 0.66
11 = Normal bias x 0.75
ADC Oversampling Ratio
0 = Low Power (64 x fs)
1 = High Performance (128 x fs)
Note that the Low Power options is not
supported when CLK_SYS_MODE=10
