While DAC_POWERUP is set, this allows the DAC to be put into left only mono
operation for power savings.
0x0 = Mono (left only)
0x1 = Stereo
Power up the simple (low power) digital supply regulator. After reset, this bit can be
cleared IF VDDD is driven externally OR the primary digital linreg is enabled with
LINREG_D_POWERUP
0x0 = Power down
0x1 = Power up
Power up the circuitry needed during the power up ramp and reset. After reset this bit
can be cleared if VDDD is coming from an external source.
0x0 = Power down
0x1 = Power up
Power up the VDDC chargepump block. If neither VDDA or VDDIO is 3.0 V or larger
this bit should be cleared before analog blocks are powered up.
0x0 = Power down
0x1 = Power up
Note that for charge pump to function, either the PLL must be powered on and
programmed correctly (refer to CHIP_CLK_CTRL->MCLK_FREQ description) or the
internal oscillator (set CLK_TOP_CTRL->ENABLE_INT_OSC) must be enabled
PLL Power Up
0x0 = Power down
0x1 = Power up
When cleared, the PLL will be turned off. This must be set before CHIP_CLK_CTRL -
> MCLK_FREQ is programmed to 0x3. The CHIP_PLL_CTRL register must be
configured correctly before setting this bit.
Power up the primary VDDD linear regulator.
0x0 = Power down
0x1 = Power up
