|
RST pin This pin defaults to active high when consumed by the sensor. The property value should ensure the flags properly describe the signal that is presented to the driver.
|
|
|
INT1 pin This pin defaults to active low when produced by the sensor. The property value should ensure the flags properly describe the signal that is presented to the driver.
|
|
|
INT2 pin This pin defaults to active low when produced by the sensor. The property value should ensure the flags properly describe the signal that is presented to the driver.

Pulse configuration register
Default value: |
|
|
Pulse X-axis threshold Threshold to start the pulse-event detection procedure on the X-axis. Threshold values for each axis are unsigned 7-bit numbers with a fixed resolution of 0.063 g/LSB, corresponding to an 8g acceleration full-scale range.
Default value: |
|
|
Pulse Y-axis threshold Threshold to start the pulse-event detection procedure on the Y-axis. Threshold values for each axis are unsigned 7-bit numbers with a fixed resolution of 0.063 g/LSB, corresponding to an 8g acceleration full-scale range.
Default value: |
|
|
Pulse Z-axis threshold Threshold to start the pulse-event detection procedure on the Z-axis. Threshold values for each axis are unsigned 7-bit numbers with a fixed resolution of 0.063 g/LSB, corresponding to an 8g acceleration full-scale range.
Default value: |
|
|
Pulse time limit The maximum time interval that can elapse between the start of the acceleration on the selected channel exceeding the specified threshold and the end when the channel acceleration goes back below the specified threshold. The resolution depends upon the sample rate (ODR) and the high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and pls_hpf_en=0, the resolution is 0.625 ms/LSB.
Default value: |
|
|
Pulse latency The time interval that starts after the first pulse detection where the pulse-detection function ignores the start of a new pulse. The resolution depends upon the sample rate (ODR) and the high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and pls_hpf_en=0, the resolution is 1.25 ms/LSB.
Default value: |
|
|
Pulse window The maximum interval of time that can elapse after the end of the latency interval in which the start of the second pulse event must be detected provided the device has been configured for double pulse detection. The detected second pulse width must be shorter than the time limit constraint specified by the PULSE_TMLT register, but the end of the double pulse need not finish within the time specified by the PULSE_WIND register. The resolution depends upon the sample rate (ODR) and the high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and pls_hpf_en=0, the resolution is 1.25 ms/LSB.
Default value: |
|
|
Magnetic vector-magnitude configuration register
Default value: |
|
|
Magnetic vector-magnitude threshold most significant byte. Resolution is 0.1 uT/LSB.
|
|
|
Magnetic vector-magnitude threshold least significant byte. Resolution is 0.1 uT/LSB.
Default value: |
|
|
GPIO specifier that controls power to the device.
This property should be provided when the device has a dedicated
switch that controls power to the device. The supply state is
entirely the responsibility of the device driver.
Contrast with vin-supply.
|
|
|
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.
This property should be provided when device power is supplied
by a shared regulator. The supply state is dependent on the
request status of all devices fed by the regulator.
Contrast with supply-gpios. If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
|
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nxp,fxos8700” compatible.
