* rsc_min_threshold will be set to MIN_THRESHOLD_OVERHEAD_TIME which
* takes into account back off time + overhead from RSC/RSC_WRAPPER. The
* overhead buffer time is required to be greater than 14. For measure,
* this value assumes 18.
* overhead buffer time is required to be greater than 14. Program it
* with a higher value (3.3 ms), so it has sufficient time to complete
* the sequence in rare cases.
