Sets the SNR threshold for a valid AM Seek/Tune. If the value is zero, then SNR is not used as a valid criteria when
doing a seek for AM. The CTS bit (and optional interrupt) is set when it is safe to send the next command. This
property may only be set or read when in powerup mode. The default threshold is 5 dB.
