Datasheet - I睠 Registers
8 I睠 Registers
8.1 Control Register 1 (0Fh)
Note: The values in Control Register 1, X_register and Y_res_int register are frozen when the I?/SPAN>C address pointer is set to 0Fh, 10h or 11h.
This ensures that the Data_valid bit, X and Y values are taken at the same time. In order to get updated values from those registers, set
the address pointer to any other address.

Bit Description
7
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 I睠 ACK bit following the read out of the Y_res_int register 11h. The
readout rate and thus the power consumption is externally controlled by the host MCU.
6:4
Configure the time base of the automatic wakeup in Low Power Mode (see Table 5).
3
0 = Interrupt output INTn is enabled (default)
1 = Interrupt output INTn is disabled and is fixed to Hi-Z
2
0 = Interrupt output INTn is active 0 after each measurement (default):
- Automatically triggered in Low Power mode, depending on the time base chosen
- 450祍 after Y readout in Idle mode
The interrupt is cleared by the I睠 ACK bit after reading the Y_res_int 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 (see Figure 16).
The Dead Zone area is set by registers Xp (Reg 12h), Xn (Reg 13h), Yp (Reg 14h), Yn (Reg 15h).
The interrupt is cleared by the I睠 ACK bit after reading the Y_res_int register 11h, and will be active 0 at the next
measurement if the magnet is still in the Detection Area. In block read mode, several other bytes could be transferred
before the interrupt is cleared when the Y_res_int register is read.
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 set by the Low Power time base bit [6:4].
1
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
the value 1111 0000, then the Soft_rst bit goes back to 0 (Normal mode) once the internal reset sequence is finished.
0
0 = Conversion of new coordinates ongoing, no valid coordinate is present in the X and Y_res_int registers. Reading
those registers at that moment can give wrong values.
1 = New coordinate values are ready in X and Y_res_int registers.
