When receiving serial data, each byte of information on the SCI has an expected format. If the received message does not match this, the SCI hardware can flag an error and generate an interrupt to the CPU. This feature must be enabled and configured in software.

LIN module supports detection of framing error condition. An error flag bit is set when an expected stop bit is not found. In SCI compatible mode, only the first stop bit is checked. The missing stop bit indicates that synchronization with the start bit has been lost and that the character is incorrectly framed. Detection of a framing error generates an error interrupt if the RXERR INT ENA bit is set. LIN module supports feature to verify valid Synch Field. It helps in automatic baud rate adjustment by comparing baud rate and adjust if baud rates differ. If the synch field is not detected within the given tolerances, the inconsistent-synch-field-error (ISFE) flag will be set and an ISFE interrupt will be generated.
