HAL82x
DATA SHEET
The sensor is now calibrated for the customer applica-
tion. However, the programming can be changed again
and again if necessary.
Note: For a recalibration, the calibration procedure
has to be started at the beginning (step 1). A
new initialization is necessary, as the initial val-
ues from step 1 are overwritten in step 4.
Step 5: Locking the Sensor
The last step is activating the LOCK function by pro-
gramming the LOCK bit. Please note that the LOCK
function becomes effective after power-down and
power-up of the Hall IC. The sensor is now locked and
does not respond to any programming or reading com-
mands.
Warning: This register can not be reset!
