Parameter Description Min Value
Max
Value
Default
Value
changeGainIfThreshHigh Applicable in both peak and peak and power detect modes.
0: Gain changes will wait for the expiry of the gain update
counter if a high threshold count has been exceeded on either
the APD or HB detector.
1: Gain changes will occur immediately when initiated by HB.
Gain changes initiated by the APD will wait for the gain update
to expire.
2: Gain changes will occur immediately when initiated by APD.
Gain changes initiated by HB will wait for the gain update to
expire.
3: Gain changes will occur immediately when initiated by APD
or HB detectors.
0 3 3
agcMode
1: AGC in Peak AGC mode, power-based gain changes are
disabled.
0: AGC in Peak and Power AGC mode where both Peak
Detectors and Power Detectors are used.
0 1 1
resetOnRxon
1: AGC state machine is reset when Rx is disabled. The AGC gain
setting will use the “resetOnRxonGainIndex” after resuming the
operation.
0: AGC state machine maintains its state when Rx is disabled
and the last AGC gain index will be used after resuming the
operation.
0 1 0
resetOnRxonGainIndex The AGC index to start with when “resetOnRxon” is set as 1. 195 255 255
enableSyncPulseForGainCounter
1: Allows synchronization of AGC Gain Update Counter to the
time-slot boundary. GPIO setup required.
0: AGC Gain Update Counter free runs.
0 1 0
enableFastRecoveryLoop
1: Enables the fast recovery AGC functionality using the HB
overload detector. Only applicable in Peak Detect Mode.
0: AGC fast recovery is not enabled.

powerEnableMeasurement 1: Power Measurement block enabled.

underRangeHighPowerThresh
Threshold (negative sign assumed) which defines the lower
boundary on the stable region of the power detect gain
control mode.
0 127 10
underRangeLowPowerThresh
Offset (negative sign assumed) from
underRangeHighPowerThresh which defines the outer
boundary of the power based AGC convergence. Typically,
recovery would be set to be larger steps than when the
power measurement is less than this threshold.
0 15 4
underRangeHighPowerGainStep
Recovery
The number of indices that the gain index pointer should be
increased (gain increase) in the event of the power
measurement being less than underRangeHighPowerThresh
but greater than underRangeLowPowerThresh.
0 31 2
underRangeLowPowerGainStep
Recovery
The number of indices that the gain index pointer should be
increased (gain increase) in the event of the power
measurement being less than underRangeLowPowerThresh.
0 31 4
powerMeasurementDuration
Number of IQ samples on which to perform the power
measurement. The number of samples corresponding to the
4-bit word is 8 × 2^(pmdMeasDuration[3:0]). This value must
be less than AGC Gain Update Counter.
