36 / 50 page  36 9571A–AT42–02/10 AT42QT1111-MU/AT42QT1111-AU KEY_n_NTHR: the negative threshold for key n (where n is 0–10). The negative threshold determines how much the signal must fall (compared to the reference) before a key is considered to be “In Detect”. This level will generally need to be tuned individually for each key. To disable an individual key, set the threshold for that key to 0. KEY_n_NHYST: the negative hysteresis applied to key n detection threshold (where n is 0 – 10). Negative Hysteresis operates as a “modifier” for the negative threshold in order to provide a greater degree of control over the detection of a “Touch”. When a key signal is first detected as being under the negative threshold, the threshold is reduced by a factor corresponding to the selected negative hysteresis. This means that the key will not go in and out of detection when the signal is on the borderline between drift-compensation or touch detection. The settings for negative hysteresis are: 00 No change to negative threshold 01 12.5% reduction in negative threshold 10 25% reduction in negative threshold 11 37.5% reduction in negative threshold Default KEY_n_NTHR value: 10 counts Default KEY_n_NHYST value: 2 (25 percent) 25 KEY_6_NTHR KEY_6_NHSYT 26 KEY_7_NTHR KEY_7_NHSYT 27 KEY_8_NTHR KEY_8_NHSYT 28 KEY_9_NTHR KEY_9_NHSYT 29 KEY_10_NTHR KEY_10_NHSYT Table 7-16.
