Abstract
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 0 and a bit 1 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 0 and the bit 1 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.
