S32K312 - Can I change PIN mode at runtime?

[ssean]

Hello

I set PTC2 to CAN RX mode in pin init config.

Can I change PTC2 to EIRQ[2] during runtime ?

Without change pin init config.

And also, back to CAN RX mode during runtime ?

Thank you

Hi,

yes, you can change routing. Siul2_Port_Ip_SetInputBuffer function can be used for it. It just updates selected  MSCR.IBE and IMCR.SSS fields.

@PetrS It works! Thank you
