ANALOG LOOP-BACK MODE
In analog loop-back mode, the differential DAC output is
connected, via a loop-back switch, to the ADC input, as shown
in Figure 22. This mode allows the ADC channel to check
functionality of the DAC channel as the reconstructed output
signal can be monitored using the ADC as a sampler. analog
loop-back is enabled by setting the ALB bit (CRF:7).
Note that analog loop-back can only be enabled if the Analog
Gain Tap is powered down (CRC:1 = 0).
