This function retrieves the core control config parameters for the CFR engine. It reads the CFR mode, peak threshold,
Description
interpolation factor and the delay currently programmed into the device.
This function may be called after device initialization and the ARM processor boot up is complete.

Parameter Description
*device Pointer to the device settings structure
txChannel Target transmitter channel whose CFR control config is required to be read back
*cfrCtrlConfig Pointer to CFR control config struct which will be updated with the CFR control settings from the device

numCorrectionPulses);
Description
Valid
Description
Values
Mask consisting of 'OR'ed transmitter channels for which
0..15 the CFR core config will be applied (1 bit for each
channel).
Selects the mode in which CFR is required to operate in.
1
Currently, Mode 1 is the only supported mode.
Sets CFR delay per engine in units of samples at the CFR
129..511
input rate (JESD 204B/C transmitter rate)
Sets the target CFR peak detection and correction
threshold. The threshold is calculated as:
0..1
The peak threshold is set to 0.79 by default.
0..1 Threshold Scaler for engine CFR engine 3
0..1 Threshold Scaler for engine CFR engine 2
0..1 Threshold Scaler for engine CFR engine 1
0..1 Threshold Scaler for CFR correction
Selects the interpolation factor to be applied to CFR input
before peak detection. The CFR peak detectors can run at
1, 2, 4
a higher (interpolated) rate to enable better peak
detection.
0..5 Sets the maximum number of peaks to remove in one
group for the respective CFR engines. Default value is 5.
0..5
User needs to set this to 0 when engine is disabled. It's
suggested to have descending order of max number of
0..5
peaks where Engine1 has the highest value.
