Property 0x0703 FM_LNA_AGC_RELEASE_MS
The FM_LNA_AGC_RELEASE_MS property sets the number of milliseconds the wideband RF low-peak detector
must not be exceeded before increasing the gain of the appropriate block. The peak detectors are only sampled
once every 3 to 5 ms. If the peak detector trips, the internal counter is incremented by 4 ms. 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 in
powerup mode.
Default: 80
