11.3.1
POWER CONTROL SETTING BIAS CIRCUITS
Using a 1-bit value, the power control settings of the bias circuits of the ADC, AVC and FSDAC can be set. When this bit
is set to logic 0, the complete bias circuits of the analog front-end and the FSDAC are shut down. In this case, the
reference voltage disappears from the input of the ADCs and LNA and the output of the FSDAC, this can cause plops
but saves power.

PON_PLL
Power-on WSPLL. When this bit is logic 0: power-off; when this bit is logic 1:
power-on. Default value 0.

default value 0
13
PON_HP
Power-on headphone driver. A 1-bit value to switch the headphone driver
into power-on or Power-down mode. When this bit is logic 0: headphone
driver is powered-off; when this bit is logic 1: headphone driver is powered-on.
Default value 0.
12 and 11
default value 00
10
PON_DAC
Power-on DAC. A 1-bit value to switch the DAC into power-on or
Power-down mode. In this Power-down mode the VREF (half the power supply
voltage) will remain on the FSDAC output. When this bit is logic 0: DAC is
powered-off; when this bit is logic 1: DAC is powered-on. Default value 0.
