Multiple Interrupt S32k148 configuration

[dhirajtarole]

Hi,

I  am trying to set multiple interrupt on PORTC eg. PTC10,PTC12 ,PTC13 but it is not working correctly.

i am using below method to install ISR.

But while using PORTD--> PTD31 and PORTC -->PTC12 it is working fine.

Query - i want to use multiple interrupt of same port (eg. from PORTC --> PTC10,PTC12....etc).

EVB - S32K148

SDK 3.0.0

Hi @dhirajtarole 

The interruption is just defined per port that’s why when you are trying to implement multiple interrupts on the same port, it does not work but when using different port it does.To work with multiple interruptions in the same port, you must check which pin of the port has its interrupt flag enabled in handler function.

You can see the pins that have received an interrupt on register PORT_ISFR, section 12.5.6 of the RM.
