Property 0x070C AM_RF_AGC_ATTACK_MS
The AM_RF_AGC_ATTACK_MS property sets the number of milliseconds the wideband RF high-peak detector
must be exceeded before attenuating the appropriate block. The peak detectors are only sampled once every 3–
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: 8
Units: ms
