LPC17xx/40xx Cyclic Redundancy Check (CRC) generator example

Detailed Description

Example description
The CRC example demonstrates using the CRC engine for 8-bit, 16-bit, and 32-bit CRC computation. The CRC engine will run via CRC computations for 8-bit, 16-bit, and 32-bit blocks and verify the CRC checksum. The expected and actual results of the test are output on the UART. If the test fails, the LED will be on.

Special connection requirements
There are no special connection requirements for this example.
