6.3.7.9 Magnetic Field Threshold Check

This diagnostic mechanism allows the controller to monitor the external applied field. The controller can use this check to determine if a magnetic field is present within specified thresholds. This check, though used as check at system level, can also indicate any gross problems with the signal path if a field much outside the expected range is detected and reported.

To run this check, the controller must enable the check separately for each axis and also set the thresholds for each axis independently. The user can configure the ALERT pin to toggle if the threshold crossed, which is also reported in the user register.

Run ModeEvery time a magnetic measurement is initiated and completed
Configuration Register(s)X_HLT_EN, Y_HLT_EN, Z_HLT_EN to enable test. X_THRX_CONFIG, Y_THRX_CONFIG, Z_THRX_CONFIG to set threshold
Fault Register Bit XCH_THX, YCH_THX, ZCH_THX
Impact if disabledDisabling this check does not have an impact on device-level failure detection but can impact at system level. Examples of system failure can be loss of magnet, magnet too far, or too close to the sensor.
