Hi Christine,
No. Interrupt resource are shared with several external pin interrupts.
Interrupt resource is called SRN(Service Request Node) in AURIX.
In TC2XX and TC3XX, only 4 SRNs can be used for external pin interrupts.
Related Service Request Control Registers are below.
TC2XX : SRC_SCUERUm(m=0..3)
TC3XX : SRC_SCUERUx(x=0..3)
If they are needed more external edge and level interrupts then they can be generated in an indirect way via GTM/TIM.
Hope this helps!
Best regards
