referring to the LSM303C data sheet, I'd like to know what exactly is to be understood with "The system can generate an interrupt signal for ... magnetic field detection".
I am interested in an application where we can use the magnetometer's interrupt to wake up on a device rotation (i.e. when the measured direction of earth's magnetic field changes).
From the data sheet I know that a positive threshold value R for interrupt generation can be configured using the registers INT_THS_L_M and INT_THS_H_M.
My question is, if R is absolute (i.e. magnetic field in X, Y or Z direction is >R or <-R) or relative (i.e. deviation since interrupt activation in X, Y or Z direction is >R or <-R).
Thank you and kind regards,
