General Description

The default use of the Cyclic Redundancy Check (CRC) component is to compute the CRC from a serial bit stream of any length. The input data is sampled on the rising edge of the data clock. The CRC value is reset to 0 before starting or can optionally be seeded with an initial value. On completion of the bitstream, the computed CRC value may be read out.

Required Software: PSoC Creator v1.0 Beta 5 and above
