to the user application to indicate that a White Light event has occurred and associated false motion
event(s) may have been suppressed by the Engine. This bit is set by the Engine and must be cleared
by the user application. The threshold or amount of light required to trigger a White Light event is
controlled by the White Light Threshold bits in PIR Status/Control Register 2.
be ignored by the user application.
Without Anti-Jam a constant source of white light events can indefinitely inhibit motion detection. With
Anti-Jam enabled, after 12 White Light events within a short duration, the Engine will begin to ignore
them and return to regular motion detection. After a period of no White Light events, the Engine will
begin looking for White Light events again. The feature is intended to prevent malicious jamming of
the detector.
