Part Number: TMS320F28069

I'm going to use UART, CAN, SPI in same micro-controller. Is there any possibility to data distort one communication by other according to the interrupt priorities? If it is distort the what are the possible solutions that reduce the distortion. thank you.

    By “distort”, I presume you are referring to data corruption. No, interrupt priority, in itself, will not lead to any corruption. If you don’t service the interrupts fast enough, there is a possibility that older data may be overwritten by newer data. Peripherals typically trigger an interrupt when such a condition is detected.
