Abstract
A method and an optical sensor are described herein. The optical sensor may include a communication interface for receiving data from a control unit and for transmitting data to the control unit, a storage unit with at least one register for storing data, and a CRC generator for generating a CRC checksum. The optical sensor may be configured in such a way that when data stored in the storage unit is to be transmitted to the control unit, the communication interface receives from the control unit a device address specific to the optical sensor and an address of a register in which the data to be transmitted is stored. The CRC generator may be initialized using the device address received from the communication interface and/or the register address received from the communication interface, before the CRC generator generates a CRC checksum for the data to be transmitted.
