Table 24. Miscellaneous Configuration 1 Register
Table 25. Detection/Classification Pushbutton Register
The Miscellaneous Configuration 1 register (R17h,
Table 24) is used for several functions that do not
cleanly fit within one of the other configuration catego-
ries. On a power-up or after a reset condition, this regis-
ter is set to a default value of A0h. Therefore, by default,

INT_EN (R17h[7]) is set to 1 enabling INT functionality.
If INT_EN is set to 0, interrupt signals are disabled and
INT is set to a high-impedance state. If DET_CHG is
set to 1, detect events are only be generated when the
result is different from previous results (by default it is
set to 0).
