1 : Idle mode
0 : Low Power mode
Low Power readout time base register
Disables the interrupt functionality.
1 : Interrupt disabled
0 : Interrupt enabled
Interrupt control register
0 : Interrupt goes low with every new calculated
x/y coordinates
1 : Interrupt pin goes low in when new x/y
coordinates are calculated and the magnet has
exited the xp, xn, yp, yn threshold values
