11.6. Locking of the Sensor
For reliability in service, it is mandatory to set the LOCK bit after final adjustment and
programming.
The success of the LOCK process should be checked by reading the status of the
LOCK bit after locking.
It is also mandatory to check the status bit of the received data or read/check the
EEPCTRL register after each store sequence to verify if the programming of the sensor
was successful.
Electro-static discharges (ESD) may disturb the supply voltage during programming.
Please take precautions against ESD.
For the programming during product development and also for production purposes, a
programming tool including hardware and software is available on request. It is recom-
mended to use the Micronas tool kit for an easy product development.
Note: It is not possible to write or to read a register after locking.
