Time base bit[2]
0 = Low Power Mode
The measurements are triggered with an internal low power oscillator – the user can select between 8 different timings by
setting the low power timebase (Control Register 1 [6:4])
1 = Idle Mode (default)
A new measurement cycle is started after the I²C ACK bit following the read out of the Y-coordinate 11h. The readout rate
and thus the power consumption is externally controlled by the host MCU.
Low Power time base
Configure the time base of the automatic wakeup in Low Power Mode
0 = Interrupt output INTn is enabled (default)
1 = Interrupt output INTn is disabled and is fixed to ‘1’ (Hi-Z)
0 = Interrupt output INTn is active ‘0’ after each measurement (default):
The interrupt is cleared after the I²C ACK bit following the read out of the Y-coordinate 11h. In block read mode, the
several other bytes could be transferred before the interrupt is cleared.
1 = Interrupt output INTn is active ‘0’ when the movement of the magnet exceeds the Dead Zone area
The Dead Zone area is set by registers Xp (Reg 12h), Xn (Reg 13h), Yp (Reg 14h), Yn (Reg 15h).
The interrupt is cleared after the I²C ACK bit following the read out of the Y-coordinate 11h, and will be active ‘0’ at the
next measurement if the magnet is still in the Detection Area. In block read mode, the several other bytes could be
transferred before the interrupt is cleared.
It is recommended to use this mode with the Low Power mode (Idle = 0), in order to wake up automatically a system
when the magnet has been moved away from the center. The polling time is the Low Power time base bit [6:4].
0 = Normal mode (default)
1 = Reset mode. All the internal registers are loaded with their reset value. The Control Register 1 is loaded as well with
0 = Conversion of new coordinates ongoing, no valid coordinate is present in the X and Y_res_int registers. Reading
1 = New coordinate values are ready in X and Y_res_int registers.
