To initialize the CRC Module and initiate a CRC16-CCITT calculation, follow this procedure:
Freescale Semiconductor
1. Write high byte of initial seed value to CRCH.
2. Write low byte of initial seed value to CRCL.
3. Write first byte of data on which CRC is to be calculated to CRCL.
4. In the next bus cycle after step 3, if desired, the CRC result from the first byte can be read from
5. Repeat steps 3-4 until the end of all data to be checked.
CRCH:CRCL.
