35.12 Checksum (Full-Featured UARTs Only)

This section does not apply to the LIN mode, which handles checksums automatically.

The transmit and receive checksum adders are enabled when the C0EN bit is set. When enabled, the adders accumulate every byte that is transmitted or received. The accumulated sum includes the carry of the addition. Software is responsible for clearing the checksum registers before a transaction and performing the check at the end of the transaction.

The following examples illustrate how the checksum registers can be used in the Asynchronous modes.
