13 CRC - Cyclic Redundancy Check Module with Memory Scanner

The Cyclic Redundancy Check (CRC) module provides a software-configurable hardware-implemented CRC checksum generator. This module includes the following features:

• Any standard CRC up to 16 bits can be used
• Configurable polynomial
• Any seed value up to 16 bits can be used
• Standard and reversed bit order available
• Augmented zeros can be added automatically or by the user
• Memory scanner for fast CRC calculations on program memory user data
• Software loadable data registers for communication CRCs
