Example program for EVAL-CN0540-ARDZ: System Default Configuration

The Circuit Note CN-0540 says:

System Default Configuration

A default configuration of the system for narrow bandwidth measurement was chosen as follows for the ADC settings:

 MCLK divider: MCLK/16

 Power mode: low power mode

 FIR filter with decimation over 32

 VCM pin output: (AVSS − AVDD)/2

 Reference (REF) buffers: precharge on

 Analog input (AIN) buffers: precharge on

 MCLK frequency of 16.384 MHz

 FDA enabled, in low power mode

 DAC buffer enabled

 DAC output set to half scale

[emphasis mine]

I'm trying to figure out how the FDA default is supposed to be Low Power Mode. Looking at the schematic, I see 

I'm not entirely sure, but I think this hardware sets the FDA to Full Power Mode by default. There is also this:

so I believe that the software can override the hardware default FDA power mode by writing to GPIO3. However, I don't see anything in Example program for EVAL-CN0540-ARDZ  that would do that by default. There is a 5  - Set ADC to default config"  option, but it doesn't seem to touch the FDA. The only way that I've found to accomplish it is to 

1. 11 - Set ADC GPIOs
2. 4 - Change GPIO settings
3. 1 - Enable all GPIOs (Global enble)
4. 11 - Set ADC GPIOs
5. 3 - Set GPIO as input / output
6. 5 - Set GPIO3
7. 2 - Set GPIO3 as output

So, in what sense is FDA Low Power Mode the system default? What am I missing?
