DATA SHEET
HAC 830
GP Register
This register can be used to store some information, like production date or customer
serial number. Micronas will store production lot number, wafer number and x,y coordi-
nates in registers GP1 to GP3. The total register contains four blocks with a length of
13 bit each. The customer can read out this information and store it in his production
data base for reference or he can store own production information instead.
Note
This register is not a guarantee for traceability.
To read/write this register it is mandatory to read/write all GP register one
after the other starting with GP0. In case of writing the registers it is neces-
sary to first write all registers followed by one store sequence at the end.
Even if only GP0 should be changed all other GP registers must first be
read and the read out data must be written again to these registers.
LOCKR
By setting the 1-bit register all registers will be locked, and the sensor will no longer
respond to any supply voltage modulation. This bit is active after the first power-off and
power-on sequence after setting the LOCK bit.
Warning This register cannot be reset!
D/A-READOUT
This 14-bit register delivers the actual digital value of the applied magnetic field after the
signal processing. This register can be read out and is the basis for the calibration pro-
cedure of the sensor in the system environment.
Note
The MSB and LSB are reversed compared to all the other registers. Please
reverse this register after readout.
