Dual Pyro Mode (Bit 0)
PIR ADC conversion rate for the Pyroelectric Sensor; controlled by the application.
• The PIR Engine performs the necessary ADC conversions on the PIR sensor input. Each conversion
• In Normal Scan Rate Mode (PIR Scan Rate set to 0), the Z8FS021 ADC peripheral is set to
• When Low Scan Rate Mode is selected by setting this bit to a 1, continuous conversion mode is
• In Low Scan Rate Mode, the ADC is disabled between conversions to reduce power consumption.
• Although the Low Scan Rate Mode provides the application with more processing power and the

Dual Pyroelectric Sensor Signaling Mode; controlled by the application.
• This bit determines if the PIR Engine should accept signals from one or two pyroelectric sensors.
• When configured for single pyro operation, only one sensor is used (connected to ANA2). When

system clocks. In this mode, the application is only required to execute the EPIR_ADC_ISR macro
for each ADC interrupt. The ADC continually runs and continuously generates interrupts.
disabled and the ADC is operated in single-shot mode such that each conversion takes 5129 system
clocks to complete. In this mode, the application software must initiate the ADC conversion request
(set bit 7 of ADCCTL0) and execute the EPIR_ADC_ISR macro once every 5mS.
Power consumption can be reduced further if the application software uses this mode in conjunction
with the CPU’s Halt or Stop modes. Alternately, this mode can be used to provide the application
software with additional CPU processing time.
opportunity for the system to reduce power consumption, the normal scan rate will provide better
sensitivity and range. While operating in Low Scan Rate Mode, sensitivity is reduced by
approximately 20%. The performance of Direction Detection can also be reduced in this mode. EMC
immunity is disabled while in Low Scan Rate Mode.
up to 200mS to avoid potential false motion detection. When changing the PIR Scan Rate mode, the
Advanced API registers must first be updated with the appropriate values.
configured for dual pyro operation, the Engine will scan two sensors simultaneously. Dual pyro mode
is typically used to provide a larger area of coverage. The second pyroelectric sensor is connected to
input ANA3. In Dual Pyro Mode, motion on either sensor will generate a motion detected event.
0 = Normal Scan Rate Mode
1 = Low Scan Rate Mode
