Typical values: For most touch applications, use the values shown in the outlined cells. Bold text items indicate default settings. The number to send to the QT is the number in
the leftmost column (0...15), not numbers from within the table. The QT uses lookup tables to translate the 0.. .15 to the parameters for each function.
NRD is an exception: it can range from 0...254 which is translated from 1 = 0.5s to 254 = 127s, in increments of 0.5s, with zero = infinity. 255 is illegal.
AWAKE is an exception: it can range from 1...255 which is translated from 1 = 0.1s to 255 = 25.5s , in increments of 0.1s. Zero is illegal.
DHT is an exception: it can range from 0...255 which is translated from 1 = 0.1s to 255 = 25.5s , in increments of 0.1s. Zero will disable DHT.
