Mixed Interrupt Signal Problem

[XiaoPing_Yang]

Hi  Sir ,

      Now I am using two external interrupt   on one port . 

      The output message "Cannot assign 'DIO3(0)' with Interrupt Signal DIO3 to physical .port 2 where 'DIO0(0)' with Interrupt Signal DIO0 is already placed." How to solve the problem .

       Thanks.

Hi xiaopingyang_1543386​,

There can be only one dedicated interrupt per port. You can do the following to resolve this issue:

If the pins are homogeneous :

    a) Use a single Pin component.

    b) Make the no of pins to 2.

    c) Check dedicated interrupt check box

    d) Connect one ISR component to the pin component.

    e) There is only one interrupt handler in this case. You can use <Pin_Component_alias>_ClearInterrupt() to know which pin triggered an interrupt and perform action accordingly
