Zusammenfassung: | A sensor includes a sensing element to produce a sensing element signal and a processor responsive to the sensing element signal to generate a sensor output signal comprising a Single Edge Nibble Transmission (SENT) frame. The SENT frame includes a Status and Communication (SCN) nibble comprising a bit and a bit that represent a status of at least one internal diagnostic indicator and a plurality of data nibbles. At least one of the plurality of data nibbles includes a cyclic redundancy check (CRC), the CRC being an encoding of the bit and the bit of the SCN nibble and the plurality of data nibbles and at least one of the plurality of data nibbles includes a count that indicates a new frame, the CRC being at least a five bit value. |
