Description
All of the KEELOQ® Encoders share the same standard code word format composed of a basic set of 65 bits of information. Although, the Advanced Encoders (e.g. HCS360, HCS361) supplement that set with extra bits of information along with a pair of CRC bits (Cyclic Redundancy Check). This Technical Brief presents a routine in PICmicro ® microcontroller (MCU) assembly language that implements the CRC polynomial as used by Advanced KEELOQ Encoders and allows a KEELOQ receiver to verify the received code word.
