However, many product makers uses only fWriteBoosterBufferFlushEn, because this can reportedly cover most scenarios and there have been some reports that flush by fWriteBoosterEn could lead raise power consumption thanks to unexpected internal operations. So we need a way to enable or disable fWriteBoosterEn.
