Extended Detection Level (Bits 7-6)
Engine Disabled (Bit 5)
Sets the sensitivity level of the extended detector; controlled by the application.
• These 2 bits enhance the motion detection algorithms to detect slower, faster and/or more subtle
• The Extended Detection level effects user control over the range provided in ePIR_SC2. As the
PIR Engine Disable/Suspend Acknowledged; controlled by the PIR engine.
• This bit indicates the operational status of and is controlled by the PIR engine. When the engine is
motion. The Extended Detection level is selected to provide a balance between additional sensitivity
while maintaining stability (no false detections). In certain applications such as lighting control the
Extended Detection level can be increased once ‘normal’ motion has been detected. Extended
detection is dependent on the lens pattern used. Smaller lens beams tend to provide more subtle
motion detection.
Extended Detection level is increased, the Range setting becomes less effective.
initialized and enabled by loading the PIR Enable Register with the ePIR_ENABLE_PATTERN value,
this bit is cleared to indicate that the Engine is ready. When the Engine is disabled by loading the PIR
Enable Register with the ePIR_DISABLE_PATTERN, it will respond by setting this bit to 1 and
perform no further operations until re-enabled. In order for the Engine to detect that it has been
disabled, the user must allow the Engine ADC interrupt to run at least once after loading the PIR
Enable Register with the ePIR_DISABLE_PATTERN.
00 = Extended Detection Level 0 – Minimum (least sensitive).
01 = Extended Detection Level 1.
10 = Extended Detection Level 2.
11 = Extended Detection Level 3 – High (most sensitive).
0 = Engine is enabled and operational.
1 = Engine is disabled and not operational.
