This ADC-specific mode defines the case where the device is fully regulated and the normal peripheral clock
is stopped. In this case, the ADC can run using its internally generated asynchronous ADACK clock.
Analog modules must be in their low-power mode when the device is operated in this state.
This ADC-specific mode defines the case where the device is in loose regulation and the normal peripheral
clock is stopped. In this case, the ADC can only be run using its low-power mode and internally generated
asynchronous ADACK clock.
