If the SCI RX buffer receives new data before the previous data has been read, the existing data will be overwritten and lost. If this occurs, the SCI hardware can flag the error and generate an interrupt to the CPU. This feature must be enabled and configured in software.
LIN module supports detection of data overrun condition. An error flag bit is set when the transfer of data from receive shift register to receiver data buffer register overwrites unread data already in received data register. Detection of an overrun error also causes the LIN to generate an error interrupt if the SET OE INT bit is one.
