Read Uncommitted. This is the lowest isolation level there is.

If the strength of the reference signal is less than this value, the sample rate calibration will be temporarily disabled (important if you use 15625 Hz as reference and someone turns the TV off !). A typical value is -80 dBfs, wich means 80 dB below the maximum level which can be handled by the ADC).
