The software also has the option to turn off the AFE power by writing to the ADC_CONTROL[4] PD bit. By default, after the initial power on the AFE is powered down and software is responsible for turning it on.

It is the software’s responsibility to empty the FIFO before requesting the ADC to enter sleep state.
