MSP430FR6043: USS ADC Raw data

Tool/software:

Hello,

MCU: MSP430FR6043

I want to read the USS ADC raw data to find the minimum and maximum values of the output signal. I retrieved the data (pCapturesBuffer and maxCapture) from the structure below.

__persistent USS_Capture_Configuration ussCaptureConfig = {
    .overSampleRate = USS_OVER_SAMPLE_RATE,
    .sampleSize = USS_USER_CONFIG_NUMBER_OF_SAMPLES_PER_CAPTURE,
    .gainRange = USS_GAIN_RANGE,
    .enableWindowHiComp = USS_ENABLE_WINDOW_HI_COMP,
    .enableWindowLoComp = USS_ENABLE_WINDOW_LO_COMP,
    .windowHighThreshold = USS_WINDOW_HIGH_THRESHOLD,
    .windowLowThreshold = USS_WINDOW_LOW_THRESHOLD,
    .agcConstant = USS_AGC_CONSTANT,
    .pCapturesBuffer = &gUSSLEATempMemBlock[0],
    .maxCapture = (sizeof(gUSSLEATempMemBlock) / sizeof(int16_t)),
    .isCapAccumulationEnabled = USS_SW_LIB_ENABLE_ACCUMULATION,
#if USS_SW_LIB_APP_MAX_ACC_BLOCK
    .pAccCaptureBuffer = &gUSSLEARAMReservedAccMemBlock[0],
#endif
};

In the code (see below), I created a new pointer to reference the pCapturesBuffer address and used it to perform the minimum and maximum value computation.

    waterQualitydata.dataLength=gUssSWConfig.captureConfig->maxCapture;
    waterQualitydata.TemppCapturesBuffer=ussCaptureConfig.pCapturesBuffer;
    waterQualitydata.adcMin=*waterQualitydata.TemppCapturesBuffer;
    waterQualitydata.adcMax=*waterQualitydata.TemppCapturesBuffer;
    for(i=0;i<waterQualitydata.dataLength;i++)
    {
        if(waterQualitydata.adcMax<*waterQualitydata.TemppCapturesBuffer)
        {
            waterQualitydata.adcMax=*waterQualitydata.TemppCapturesBuffer;
        }

        if(waterQualitydata.adcMin>*waterQualitydata.TemppCapturesBuffer)
        {
            waterQualitydata.adcMin=*waterQualitydata.TemppCapturesBuffer;
        }
        waterQualitydata.TemppCapturesBuffer++;
    }

After the implementation, FRAM consumption increased by 6.4 KB, solely due to the above code changes.

Could you please help me analyze this.
