Notes: Bold text items indicate default settings. The number to send to the QT2640 is the index number in the leftmost column (0 – 15), not numbers from the
table. The QT2640 uses a lookup table internally to translate the indices 0 – 15 to the parameters for each function.
LSL is an exception: Ranging from 0 to 2047, its value is used directly and without any translation.
