7.3.2 Device Output
If the device is powered on with a magnetic field strength between B_RP and B_OP, then the device output is
indeterminate and can either be Hi-Z or Low. If the field strength is greater than B_OP, then the output is pulled
low. If the field strength is less than B_RP, then the output is released.
