MSP430FR6047: How to retrieve DTofOffset

Part Number: MSP430FR6047

MSP430FR6047

We are calibrating deltaTofOffset on demand at run-time, using the following code:

    // Re-calibrate offset
        if (cal_offset)
        {
            cal_offset = false;
           
            USS_updateDtoFOffset(&gUssSWConfig, 0.0f);
            code = USS_calculateOffsets(&gUssSWConfig, &abstoFDtofTestResults,
                                &abstoFDtofTestConfig);
            checkCode(code, USS_message_code_no_error);

            if (code == USS_message_code_no_error)
            {
                //code = USS_updateDtoFOffset(&gUssSWConfig, (-1.0f * abstoFDtofTestResults.dToFOffset));
                code = USS_updateDtoFOffset(&gUssSWConfig, (  abstoFDtofTestResults.dToFOffset));
                checkCode(code, USS_message_code_no_error);
                if (code == USS_message_code_no_error)
                {
                    g_offset = abstoFDtofTestResults.dToFOffset;
                }
            }
        }

Does USS_updateDtoFOffset() store the new offset in persistent memory?  It seems to, since the effect on volume flow rate persists through a power cycle.

Is there a way to retrieve the dToFOffset at power up?

Thanks
