The description of the VCCLO pin says it goes low when Vcc is below Vth+.However, the timing diagrams 20 and 21 show VCCLO going low tdebounce after VCC drops below Vth-.Which is correct?
How are the Activity/Inactivity registers used? ACT_THS (04h) and ACT_DUR (05h)Can the LSM9DS1 be configured to automatically go to low-power mode, or does the host need to do that?
Is it possible to generate an interrupt on INT_M when the Magnetometer data is ready (in the same way you can with the Acc/Gyro)?
How do the LSM9DS1 DRDY_M and DEN_A/G pins function?
In the LSM9DS1, what is the relationship between the interrupt threshold register INT_GEN_CFG_XL (8 bits) and the output register OUT_X_XL (16 bits)?
