Refer to the direct-page register summary in the Memory chapter of this data sheet for the absolute address
assignments for all CRC registers. This section refers to registers only by their names. A
Freescale-provided equate or header file is used to translate these names into the appropriate absolute
addresses.

A 16-bit CRC result and seed register (CRCH:CRCL)
CRCH — This is the high byte of the 16-bit CRC register. A write to CRCH will load the high byte of the initial 16-bit
seed value directly into bits 15-8 of the shift register in the CRC generator. The CRC generator will then expect the
low byte of the seed value to be written to CRCL and loaded directly into bits 7-0 of the shift register. Once both seed
bytes written to CRCH:CRCL have been loaded into the CRC generator, and a byte of data has been written to
CRCL, the shift register will begin shifting. A read of CRCH will read bits 15-8 of the current CRC calculation result
directly out of the shift register in the CRC generator.
