Part Number:AWR2944EVM

In the millimeter wave demo Mentioned in mmwave_mcuplus_sdk_04_02_00_02， there is function named 'DPU_DopplerProcHWA_configHwaCFARAzimFFT' which is called by the function named 'DPU_DopplerProcHWA_config' used by doppler DPU module

in the function DPU_DopplerProcHWA_configHwaCFARAzimFFT，the total number of HWA paramSets used is defined by ’DOPPLERPROCHWA_DDMA_AZIMCFAR_NUM_HWA_PARAMSETS which is equal 8,But the actual number configured in the code is 10,Why?
