LIN driver alters GPIO in UART mode

[ianchuter]

Hi 

I have an application running which communicates successfully using the LIN driver on a S9KEAZN16AMLH, however, while the LIN is communicating, the GPIO state is cleared apparently randomly - this stops if the LIN communication stops. The LIN is using UART, so does anyone know why it would be altering the GPIO state?

Hi

Thanks for your reply. This turned out to be an issue with my code - if the interrupt occurred at a certain point the GPIO was being left in a mess - I've restructured this part of my application and it can now ride out the interrupts without issue.

Hi lan Chuter,

   Do you mean when the LIN UART pin works, the according GPIO input status also changing?

  If yes, the phenomena is correct, because even you configure the pin to other modules function, the GPIO input status also works, it is correct.

Have a great day,
Kerry
