... Setting NDIL = 0 for a key disables it (Section 6.5 time can the number of enabled keys exceed the maximum specified for the device (see Section 1.2). On the QT60160, only the first 2 Y lines (Y0, Y1) are operational by default. On the QT60160, to use keys located on line Y2, one or more of the pre-enabled keys must be disabled simultaneously while enabling the desired new keys ...

... The QT60160/QT60240 allows multiple byte transmissions to provide a more efficient communication. This is particularly useful to retrieve several information bytes at once. Every time the host retrieves data from the QT60160/QT60240, an internal address pointer is incremented. Legend Units Therefore, the host only needs to write the initial address ...

Specifically, drift compensation should be set to compensate faster for increasing signals than for decreasing signals. Decreasin g signals should not be compensated quickly, since an approaching finger could be compensated for partially or entirely before even touching the touch ...
