Version: **

A dedicated interrupt resource cannot be assigned for each pin with an external pin interrupt. Interrupt resources are shared with several external pin interrupts.
Interrupt resource is called Service Request Node (SRN) in AURIX™.
In TC2XX and TC3XX, only four SRNs can be used for external pin interrupts.

Following are the related Service Request Control Registers:

TC2XX: SRC_SCUERUm(m=0-3)
TC3XX: SRC_SCUERUx(x=0-3)

If the customer requires additional external edge and level interrupts, then the additional interrupts can be generated using the General Timer Module (GTM) / Timer Input Module (TIM).
For more details, see the “Interrupt Router (IR)” section of the User’s manual.

Note:

This KBA applies to the following series of AURIX™ MCUs:

AURIX™ TC2xx series
AURIX™ TC3xx series
