In the project of FLEXIO_UART_S32K144, , please help to assess whether there is a risk of FLEXIO_UART_DRV_CheckStatusTx. If the function of FLEXIO_UART_DRV_CheckStatusTx is set with a high bort rate of serial port, communication will fail if this code is not shielded.Can I block it?
This part of the code is to ensure that the timer gets an interruption when the transmission is complete. If you comment this part, the interruption won't be enabled.
If you have more questions do not hesitate to ask me.
