Overview
This group box displays any interrupt or status that have occurred on the device.
Reset all status flags on next write resets all status to idle mode after the tab write.
8. Sensor Control Register
Allows the selection of any sensor to be sampled. Selection of one or multiple sensors is possible.
9. Reference / ADC1 Sensor
Analog Input. If "Using Thermistor", check 11. This causes the input to be configured for an external
reference resistor measurement. Otherwise, it can function as a standalone generic analog sensor
(ADC1).
10. Thermistor / ADC2 Sensor
Analog Input. If "Using Thermister", check 11. This causes the input to be configured for an external
thermistor measurement. Otherwise, it can function as a standalone generic analog sensor (ADC2).
11. Using Thermistor
If using a thermistor, this option must be selected for the application ROM code to properly set up the
measurement.
12. ADC0 / Light Sensor
When using a RF430FRL152HEVM, this is an option to sample the light sensor. Otherwise, it is a
generic analog sensor (ADC0).
13. Internal Temperature Sensor
Allows sampling of the internal temperature sensor on the part.
14. Digital Sensor 1
If using the RF430FRL152HEVM together with the Sensor Hub BoosterPack, this samples the SHT21
temperature sensor. Otherwise, it is an option to sample a generic digital sensor.
15. Digital Sensor 2
If using the RF430FRL152HEVM together with the Sensor Hub BoosterPack, this samples the SHT21
humidity sensor. Otherwise, it is an option to sample a generic digital sensor.
16. Digital Sensor 3
If using the RF430FRL152HEVM together with the Sensor Hub BoosterPack, this option samples the
ISL29023 light sensor. Otherwise, it is an option to sample a generic digital sensor.
17. Number of Passes Register
One pass is sampling all of the selected sensors one time.
18. Averaging Register
Any value higher than 1 causes that many samples to be averaged into one result. Averaging mode in
the "Alarm Control" tab selects the type of averaging used per sensor.
19. Frequency Register
Selects the delay to be made in between each of the sampling passes. Note this delay must not be
less than the time to complete sampling all of the sensors one time. If it is less, then a "collision"
occurs.
20. More Registers
This advanced section is not required in most cases. However, it is described below.
Gating option to enable the external GPIO interrupt.
21. Interrupt Assert Level
The level to be driven or pulled to if there is an interrupt
22. Interrupt Drive State
Determines if the device drives an interrupt or is high impedance (user must provide the appropriate
pullup or pulldown resistor).
23. Bus Test Mode Enable
Allows access to protected memory using an I
2
C or SPI host.
