TMS320F28377D: DAC_tuneOffsetTrim

Hello everybody,

TechRef SPRUHM8 refers to the funtion "DAC_tuneOffsetTrim", which is part of the C2000ware driverlib.
This function can be used to adjust the DACTRIM value if DAC is operating with a different ref than 2.5V .

My question:

After executing this function, is the new TRIM-value stored in the the TRIM-Register and the 2.5V-REF-TRIM-value is lost?

Or is the original 2.5V-REF-TRIM-value reloaded into the TRIM-Register after RESET?

Thanks in advance,

Jan
