SDL MCRC Semi CPU
Introduction
This example demonstrates the usage of the MCRC module. The example shows how to setup and use the MCRC controller in the semi mode of operation. Shows the generation of matching CRC as well as non-matching signature due to insertion of error in the block of information on which the CRC is being performed or in the signature provided to the PSA Signature Register (or both, depending on the mode).
