Cyclic Redundancy Check (S08CRCV1)
8.1 Introduction
The MC9S08AC60 Series includes a CRC module to support fast cyclic redundancy checks on memory.
8.1.1 Features
Features of the CRC module include:
⢠Hardware CRC generator circuit using 16-bit shift register
⢠CRC16-CCITT compliancy with x16 + x12 + x5 + 1 polynomial
⢠Error detection for all single, double, odd, and most multi-bit errors
⢠Programmable initial seed value
⢠High-speed CRC calculation
⢠Optional feature to transpose input data and CRC result via transpose register, required on
applications where bytes are in LSb (Least Significant bit) format.
