Interrput line number configuration nRF5340

Question

Hi,

I faced some issues regarding multiple IRQ_CONNECT being onvoked on the same irq and I went into this post :

LPUART nRF5340 fatal error - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

Does it means that any <PERIPHERAL>X interrput can be re-routed to any <PERIPHERAL>Y line?

For instance, I use TWIM0, and I assume following code is not valid :

&i2c0 {
    compatible = "nordic,nrf-twim";
    status = "okay";
    pinctrl-0 = <&i2c0_default>;
    pinctrl-1 = <&i2c0_sleep>;
    pinctrl-names = "default", "sleep";
    // re-route to TWIM1 interrupt
    interrputs: <9 5>
};

What about replace &i2c0 by &i2c? I would need some clarification on this point, as the post doesn't really explain why moving GPIOTE0 interrupt line to GPIOTE1's one works.

Thank you in advance

Ben_Squar3d said: why does re-route GPIOTE IRQ to GPIOTE1 (47) instead of GPIOTE0 (9) work? 
 The problem discussed in linked Q&A seems to be about the application switching from using GPIOTE0 to GPIOTE1 after building the application for the Non Secure Processing Environment (i.e. nrf5340dk_nrf5340_cpuapp _ns) . Therefore, the harcoded IRQ number had to be changed to match the selected peripheral. 
 Could you provide a bit more information about what you are trying to achieve? 
 Best regards,
