Chargepump Source Assignment Override
0x0 = Chargepump source is automatically assigned based
on higher of VDDA and VDDIO
0x1 = the source of chargepump is manually assigned by
VDDC_MAN_ASSN
If VDDIO and VDDA are both the same and greater than
3.1V, VDDC_ASSN_OVRD and VDDC_MAN_ASSN should
be used to manually assign VDDIO as the source for
chargepump.
Reserved
Sets the VDDD lin. regulator output voltage in 50mV steps.
Must clear pwd_linreg_d bit to enable this lin reg.

Analog Ground Voltage Control
These bits control the analog ground voltage in 25mV steps.
This should usually be set to VDDA/2 or lower for best
performance (maximum output swing at minimum THD). This
VAG reference is also used for the DAC and ADC voltage
reference. So changing this voltage scales the output swing
of the DAC and the output signal of the ADC.
0x00 = 0.800V
0x1F = 1.575V
Bias control
These bits adjust the bias currents for all of the analog blocks.
By lowering the bias current a lower quiescent power is
achieved. It should be noted that this mode can affect
perfomance by 3-4dB.
0x0 = Nominal
0x1-0x3=+12.5%
0x4=-12.5%
0x5=-25%
0x6=-37.5%
0x7=-50%
VAG Ramp Control
Setting this bit slows down the VAG ramp from ~200ms to
~400ms to reduce the startup pop, but increases the turn on/
off time.
0x0 = Normal VAG ramp
0x1 = Slowdown VAG ramp
