Cyclic Redundancy Check (CRC)
20.1
The CRC block provides hardware accelleration for CRC16-CCITT compliancy with x
polynomial. It is implemented on the 8-bit peripheral bus, and provides a very simple programming
interface of only two 8-bit registers. The V1 ColdFire 8-bit peripheral bus bridge serializes 16-bit accesses
into two 8-bit accesses, so both registers can be read/written using a single 16-bit read/write instruction.
This peripheral is available in both RUN and LPRUN modes.
