1) In case you are using UDB,
You can set the LIN break length in Advanced tab of UART component configuration window.
You can use API UART_SendBreak(uint8 retMode) to send break condition.
You can use API UART_ReadRxStatus() to check if break was detected.
2) In case you are using SCB,
You can use API SCB_UartSendBreakBlocking(uint32 breakWidth) to send the break condition and width can also be set here (parameter passed).
In advanced tab of component configuration, you can enable "break detect" interrupt.
thx for your answer, I try it but without success.
I use the SCB Unit for UART, Name of the UART is "LIN".
1. There is no Break IRQ option in Advanced (see Picture)
2. I have no SCB_UartSendBreakBlocking(uint32 breakWidth) or LIN_UartSendBreakBlocking(uint32 breakWidth) API
