Noise Sensitivity (Bits 6–0)
Controlled by the application.
This register determines how sensitive the noise detection part of the engine is to random noise in the
PIR signal. A lower number makes the noise detector more sensitive, at the cost of potential rejection
of small-signal motion (for example, a small delta between ambient and target temperature or distant
target). The valid range is 0 (disabled) to a maximum value determined by the Window Size selected in
the PIR Advanced Status/Control Register 2. See Table 26.
