12.3. ECRC

ECRC ensures end-to-end data integrity for systems that require high reliability. You can specify this option under the Error Reporting heading. The ECRC function includes the ability to check and generate ECRC. In addition, the ECRC function can forward the TLP with ECRC to the RX port of the Application Layer. When using ECRC forwarding mode, the ECRC check and generation are performed in the Application Layer.

You must turn on Advanced error reporting (AER), ECRC checking, and ECRC generation under the PCI Express/PCI Capabilities heading using the parameter editor to enable this functionality.

For more information about error handling, refer to Error Signaling and Logging in Section 6.2 of the PCI Express Base Specification.
