MD Origin (Bit 2)
EM Noise Detected (Bit 1)
EM Transient Detected (Bit 0)
PS028506-1110
Origin of last motion detection event
Controlled by PIR engine
This bit indicates how the PIR engine detected the last Motion Detected Event. When the engine sets
the Motion Detected bit in PIRStatus0, it also sets this bit according to which detection engine registered
the event.
EM Noise Detected on PIR Signal
Set by PIR engine; cleared by application
This bit indicates if the engine has detected noise on the PIR signal. This event is provided to the user
application to indicate that an EM noise event has occurred and associated motion event(s) may have
been suppressed by the engine. This bit does not have to be read for normal operation and is provided
as status only. The application must clear this bit after it has been read.
EM Transient Detected on PIR Signal
Set by PIR engine; cleared by application
This bit indicates if the Engine has detected a transient on the PIR signal. This event is provided to the
user application to indicate that an EM transient event has occurred and associated motion event(s)
may have been suppressed by the engine. This bit does not have to be read for normal operation and is
provided as status only. The application must clear this bit after it has been read.
